a line has an equation?

D.  The last number is where the line crosses the Y axis, so all the others will intersect with the given line.

To answer this I must first explain what an equation is:\nAn equation is where 2 sides are equal to one another.  Ex. 4x + 13 = -91\n\nAn expression does not have the = sign.  Example: 4x + 13

there is a solution, all x,y that satisfy this equation:\ny = 4 - 2x\n\nwhich is a straight line with intercepts (0,4) & (2,0)\n\nIt has an infinite amount of solutions. To be able to solve for actual numbers, you need as many equations as you have variables.

y=-4x+k is the first line slope =-4= m\n \nsecond line has a slope-1/m=-1/-4=1/4\n\nsecond line : y=(1/4)*x+C , but C=0 because line passes through the origin\n\nline  is thus y=x/4\n\n\nsubstitute v+1 for y and v for x in this equation\n\nv+1=v/4\n\nv=-4/3

When graphed, a linear equation will form a straight line while a non linear equation will not be a straight line

For any line through 2 points (x-x1)/(y-y1)=(x2-x1)/(y2-y1); thus (x-0)/(y+5)=(8-0)/(9+5) or\nx=(y+5)*4/7 or 7x-4y-20=0 or 4y-7x+20=0 or y=1.75x-5 all are the same!

A linear equation looks like a line when it is graphed.  The standard form of the equation is y=mx+b where m is the slope, and b is the value of y at the point where the line crosses the y-axis.\n\nA non-linear equation does not look like a line.  It may look like a curve.  A non-linear equation could possibly be a parabola, a circle, a wave, a hyperbola, etc... but not a line!

Your equation would look like x^2-ax+b.  Which means when you solve the equation you would two answers one of which will contain a plus sign other will contain a minus sign since the middle term is negative.  Thus the answer is C.

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

What you have given us is an expression, not an equation.  An equation could be solved for H, however an expression can not.

The eqaution of the line is\ny-y1 =m(x-x1)\ny-0 = -3[x-(-4)]\ny-0 = -3(x+4)\ny= -3x-12

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)

Do practice .\n   do not learn formulae,\n   But see them and originate questions by yourself from it.\nlike \n   a formula for line is \n    y = mx + c;\n what happens if x = 0; what line it gives\n what happens when y = 0 :  "  "   "   "  \n if x = y                   "  "   "   "

Line AC = 6, line BC= 2x+2, line AB=x+1\nSo 2x + 2 = 6\n2x = 4\nx = 2 <-- option C

You tell an equation is linear if there's a simple relationship between "x" and "y".\n\nIf you can say that "y is 2 lots of x, plus some constant number" or "y is half of x plus some constant number", that's a linear relationship.\n\nNote that the constant number can be 0!\n\nWritten formally, that means y = ax + b, where "a" is the simple relationship and "b" is some constant number.\n\nIf you need to transform "x" in any other way, it's non-linear.

On a graph, a line can have a slope. The slope is defined as how many spaces the line moves up or down divided by how many spaces the line moves left or right from any two given points. You may see it written as\n\nrise\n----\nrun\n\nOR\n\nchange in Y\n-----------\nchange in X\n\nOR\n\n{for the line through points (X1, Y1) and (X2, Y2)}\n\nY1-Y2\n-----\nX1-X2\n\n\nA line from upper right to lower left will have a positive slope.\nFrom upper left to lower right will have a negative slope.\nStraight up and down will have an undefined slope.\nLeft to right will have a slope of 0.\n\nHope this helped! Good luck!

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...
