how do you identify the slope and y intercept?

Y=MX+B\nso identify which number is next to the X, that will be your slope.  The other number is the Y-intercept.\n\nFirst problem:\nY=-2X+3\nthe -2 is next to the X so it is the slope (M)\nthe 3 is by itself so it is the Y-intercept (B)\nthe other two problems are the same way

i don't understand your question too well because it isn't a question but i answer with\nslope intercept form(replace y with F(x)\nmakes it in function notation\nY=mx+b\nm is the slope rise over run\nx is the variable that you can plug in\nb is where the line crosses the y axis\n\nstart with a point on the y axis that is the the y intercept(b)\n\nfrom there do a slope\nexample: y=1/4x+2\n\n\n+++++++++!++++++++++ \n+++++++++!++++++++++ \n+++++++++!+++x++++++ \n+++++++++x++++++++++ start with a point at 2y\n+++++x+++!++++++++++ \n-----------------+ ------------- then move up one and right 4\n+++++++++!++++++++++ \n+++++++++!++++++++++ and a dot down one and left 4\n+++++++++!++++++++++ \n+++++++++!++++++++++ and connect the points, then you would have graphed a segment of the line and just extend that and you solve the problem for your graph

The slope should be 3 over 1 or +3(rise over run)and the x and y intercepts would both be 0  (0,0). \n\nThis can be found by using the equation y=mx+b or by using a graphing calculator. The graph of the line in this case crosses exactly where the x-axis and y-axis cross (0,0).

If you are given the slope(m) and a point on the line(x1, y1) you can write the equation of the line.\n\nYou take the y-intercept equation\ny =m*x + b and substitute x1 and y1 for x and y and get\ny1 = m*x1 + b    \nnow solve for b\nb = (y1-m*x1)\nsubstite b = (y1-m*x1) into the y-intercept equation\ny =m*x +(y1-m*x1)\nsubtract y1 from both sides of the equation\ny -y1 = m*x -m*x1\nbecomes the point-slope formula\ny -y1 =m*(x-x1)

y=mx+b\n\n"m" is the slope, and "b" is the y axis. Best wishes in your studies!

If the equation is lineear, or a line like it sounds like, the equation is y=mx+b. m is the slope or ten. and b is the y-int. or -130, and you are done

First you need to find the slope of the line, by finding two points on the line and making a fraction found by subtracting the two y-coordinates and putting this over what you get by subtracting the two x-coordinates.  Then if you can, find the y-intercept.  The equation is y = mx + b where m = slope and b = y-intercept.\n\nSuppose your trend line contains the point (4, 20) and hits the y-axis at (0,8)\n\nThe slope is (20-8)/(4-0) = 12/4 = 3\n\nThe y-intercept is 8\n\nSo the equation is y = 3x + 8

Slope intercept form:  y=mx+b where m= the slope and b= the y-intercept.\n\ny=2x-4

Hi!\n\nSo, what you are looking at is a linear equation.  You can tell this because there is only one instance of the variable x, and it is not raised to any power.  So, the graph will take the form of a line.\n\nAll linear equations take the form f(x) = mx + b\n\nWhere m is typically called the "slope" and b is called the "y-intercept".   The y-intercept is the point on the graph where the function intercepts the y-axis (the one that goes from top to bottom on the graph).  So, right away you can tell that the y-intercept in your equation is -5 (negative 5).  What this means is that the graph intercepts the y-axis at the -5, or in other words, there is a point on the graph at the location (0,-5).  You can put a dot there.\n\nThe next thing you need to see is the slope.  In you equation, the slope is -2 (negative 2).   Slope really means "rise over the run", or in other words, how much the graph rises for every point it goes to the right.  A slope of negative 2 means that for every increase in x of one unit, the y value decreases by negative 2.   \n\nSo, starting at the point (0,-5) which we determined above, go down 2 units and to the right one unit (putting you at the point (1,-7).  That's another point.  You can do it again and find the next point which is (2,-9) and put another point.  You now can put your ruler on the graph and draw the rest of it.\n\nIt's good to understand how this type of equation works.  You could have also made a table of x values and y values, and simply computed a series of y values for a series of x values (that you picked).  Then you could have drawn the graph also.  But understanding this type of equation will help you in the future.

y=mx+b\n\njust rearrange it so you get b as your intercept..\n\nin this case y=-1/4x +3, so the slope is -1/4, and the intercept is 3

Draw any line passing through origin. Its equation is y = mx and the slope ‘m’ is y/x.\n\nNow move the line up (or down) through a distance‘d’ with out changing the slope. The line cuts the y-axis at a distance d from the origin. This is y-intercept.\n\nThe x-coordinates of all the points on the line remain the same whereas all y-coordinates increase (or decrease) by‘d’. But the slope remains the same and x coordinates also remain the same. Therefore we give a correction to y coordinate to keep m constant.\n \nDenoting +d or -d by ‘b’, the slope of the new line’ ‘m’ is (y- b) /x. \n\nThus the equation of any line in slope intercept form is \n\nm =(y - b)/ x. or y = mx + b.

It has no y intercept cuz its a vertical line.\nIt's slope would be undefined cuz when you try to find the slope the normal way using two points, say (-7,4) and      (-7,8), the slope would be (8-4)/(-7-(-7))=4/0 which is undefined

That means put zero for x and see what y is (the y-intercept), then put zero for y and see what x is (the x-intercept).\n\nDraw the two intercepts and draw a line through them.

Solve for y: y=3x\n\nThe slope is 3, and the y-intercept is (0,0). (y=mx+b: m is slope, b is y-intercept)\n\nThe slope is the change of y over the change of x.\n\nStart from (0,0) and go up 3 units, right 1 unit.  Connect the points and continue the line.

The slope-intercept form for a line is y=mx+b, wherem is the slope and b is the y-intercept. Comparing this form to y=7x+3, you see that m=7 (the slope) and b=3 (the y-intercept).

you can use the y=mx+b formula for a line.  \n\ny is the y-coordinate of a point\n\nm is the slope, x is the x-coordinate of a point\n\nb is the y-intercept (where the line touches or intercepts the y-axes).  \n\nsince you know the y intercept of the line (passes through origin, so it's 0), the value of b would be 0 and  you also know the slope of the line, which is two, the equation for the line would look like this.\n\ny=2x + 0 or y=2x\n\na point on the line would have coordinates that would fit the equation ---- y has to be two times x; x has to be 1/2 of y.\n\nhere are some points on this line: (0,0), (1,2), (-1,-2), (2,4), (-2,-4).\n\nhope that helped :)

y = mx + b  --> slope-intercept form\ny = 3x + b\nsubstituting point(4, 9)\n9 = 3(4) + b\n9 = 12 + b\nb = -3\n\ntherefore the equation is given by\ny = 3x - 3
