What does the intercept of the equation of the line reveal? (What is the meaning of the intercept?)?

Well, the y-intercept would be acceleration when the force on the object is zero.  You'd better hope it's zero!  If it's not, you might want to fix the point in your analysis (this can be done in Excel) or redo the experiment.\n\nEdit: If you're plotting acceleration vs. force, the intercept really should be zero.  Those values appear small enough to be within the error of the experiment.  They could be indicative of the effect of a systematic error, but are more likely the result of random noise.  Try fixing the intercepts at zero in Exel (right-click on the regression line and open up the options for it; there should be a checkbox for "fix intercept").  An intercept value that is not equal to zero indicates that there was acceleration when there was no force!

y-intercept occurs when x=0\n\nSo, set x=0, and your equation becomes:\n    2(0) - y = 4\n\nor, because 2*0 = 0,\n    \n    y = -4 is your y-intercept.\n\nThe slope can be found by writing the equation in standard "y = mx + b" form, where "m" is the slope. In your example, that would be:\n\n    y = 2x - 4\n\nSo, the slope ("m") is 2.\n\nDone and done.

Im not gonna give u the answer, coz u wont learn otherwise, but i can tell you how to solve it...\n\nWell, remember that the standard equation for a line is \n\ny = mx + c\n\nwhere m is the slope of the line... Now, there is a relation between the slopes of two lines if they are parallel, look it up yourself...\n\nSo u have the slope of the line whose equation u need to find... U also have a point thru which it passes... Another representation of the equation of a line is...\n\ny - y1 = m(x - x1)\n\nwhere x,y are the variables for the eqn, m is the slope of the line, and x1, y1 are the (x,y) co-ordinates of a point thru which the line passes...\n\nYouve got all the stuff, throw it in, and wolla...

The Y-INTERCEPT of the line y = b is b.\n\nFor a y-intercept, you plug in 0 for the other variable, primarily x, but in this case, b.\n\nTherefore, if you plug it in, you receive:\n\ny = 0\n0 = 0\n\nThe y-intercept is 0\n\nPerhaps you should check by graphing, but I assure you that I am correct

hey, a line should always be straight. i mean, if thats not straight, it should never be called a line by then. thats what my f-uck-ing geometry teacher told me when i was 1st year hs then. im a 4th year senior here btw. and im 16.\n\na linear equation is in the form ax+by = c, where the two points your telling is the x and the y. a, b and c denotes real numbers and a and b must not be equal to zero, in one way or the other.\n\nexample is the equation y = 3 - 2x\nto solve this, you can choose either of the ff:\n\n1. Make a table of values, meaning, make a table wherein you will decide what number to put in a variable.\nin the given equation, i will use -2 , -1, 0, 1, 2 and 3 as my given values for x. substituting the values in the equation, i will arrive at answers 7, 5, 3, 1, -1, and -3 respectively.\n\nthe solution points will then be:\n(-2, 7)\n(-1, 5)\n(0, 3)\n(1, 1)\n(2, -1)\n(3, -3)\n\n2. Given the equation 3x - 4y = 12. Solve.\nSolve for the x intercept by using y=0\n3x - 4(0) = 12\n3x = 12\nx=4\n\nand solve for y using x=0.\n3(0) - 4y = 12\n-4y = 12\ny = -3\n\npretty easy huh.

Hopefully you know how to solve one part of it. Slope intercept form is Y= M x+B. First find the slope, using 2 set of coordinates, that formula is Y2-Y1 over X2-X1. that will be your M.  Then find your Y intercept. then plug it in to that formula above. I hope i was of some help. Don't put your life on this i did it in the beginning of the school year.  I may have the M and the B switched.

The slope of a line is defined as:\n\nm = (change in y) / (change in x)\n\nor:\n\nm = (y2 - y1) / (x2 - x1)\n\nGiven the points (-3, 3) and (0,-3) means:\n\nx1 = -3\nx2 = 0\ny1 = 3\ny2 = -3\n\nPlugging these numbers into the equation for m yields:\n\nm = (-3 - 3) / (0 - -3)\n\nm = (-3 - 3) / (0 + 3)\n\nm = (-6) / (3)\n\nm = -2\n\nNote that a slope of 0 means that there is no change in y, or that y1 = y2

m = 2\nb = 4\n\nThus, your line's equation is y = 2x + 4\n\nThe x-intercept occurs where the line crosses the x-axis, which is also where y = 0. Substituting 0 for y in the above equation:\n\n0 = 2x + 4\n-4 = 2x\n-2 = x (x-intercept)

They are the values that make the equation true.  If the equation is true then the equation represents a straight line.

The slope-intercept form of a line is\ny = mx + b, where m is the slope and b is the y-intercept.

The slope is zero, it is a horizontal line.  The equation is y=-3.\n\ny=mx+b is the slope intercept form where m is the slope and b in the place where the line crosses the y axis.\n\nSlope is rise over run. The is the difference in y's over the distance in x's.

This is for math right? If so:\n\nThe slope-intercept form is:\n\ny = mx + b\n\ny = value on the y-axis\nm = slope\nx = value on the x-axis\nb = y-axis intercept\n\nThe slope-intercept form gives the equation for a straight line.

general equation of a line with slope m and y-intercept c is \n\ny = mx + c ....... (1)\n\nsay this line is parallel to 2x+3y+4=0 which means the slopes of two lines are equal\n\nso, m = -2/3  [-(x-coefficient/y-coefficient)]\n\nand c = 6 (given) \n\nsubstituting m and c in (1) \n\nrequired equation is y = -(2/3)x + 6\n\n=> 2x+3y-18=0

The form y = mx + b is called the "slope-intercept" form of an equation describing a straight line.\n\nIn this form, m is the slope (how much the y-value changes for each unit change of the x value) and b is the point along the y-axis where the line crosses it (where x-value is zero).\n\nSo, as m increases, the line bocomes closer to vertical and when m decreases, the line becomes closer to horizontal.\n\nSimilarly, when b increases the line's slope remains the same but the line moves up on the graph, while if b decreases then the line moves down.\n\nHere is a great website for playing with this form of a linear equation in slope-intercept form:

The x-intercept is when the line crosses the x axis. When your equation's graph crosses the x axis, it means that y is zero at that point. right?\n\nSo to find the x-intercept you assume y=0 and solve for x.\n\nNow to find the y-intercept, it is when x=0. If you imagine it graphically, when it touches the Y-axis, X's value is zero.\n\nSo to find the y-intercept you assume x=0 and solve for y.\n\nExample: y= 3x-6\nx-interp: assume y=0\n      0= 3x -6      \n 3x = 6     \n x = 2\n\ny-interp: assume x=0 \n     y= 3*0 -6        \n          y= -6

If you're dealing with a straight line (and a few other types of line I think), the equation will be of the form\ny=mx+c\nThe c part will give you the y-intercept i.e. where the line crosses the y-axis.
