graph pairs of points, draw line, find slope-intercept eqn

[trocks94]

do you know how to do this?

graph the points and draw a line through them. write an equation in slope-intercept form of the line that passes through the points.

1.(-1,-2)(2,6)
2.(-1,-2)(3,-2)
3.(2,-3)(-3,7)
4.(6,-4)(-1,2)
5.(1,1)(7,4)
6.(5,-6)(5,-3)
7.(-5,2)(6,1)
8.(-1,10)(12,-4)

Re: HELP

Start by calculating the slopes. Then use one of the points to solve for the y-intercept.
