Question

Finish writing the equation of the line y=-1/2x+?, given the points (8, -3) and (-2, 2).

Answer 1

The equation of a slopeis y=mx+b. Because you know a point already, substitute the x coordinate into x and the y coordinate into y. For example, you'd get 2=(1/2)(2)+b.

Answer 2

okay, how do i find b?

Answer 3

2=1+b. Subtract 1 and b=1.
