Question

A line passes through the points (-1,4) and (2,-2) what is the equation of this line

Answer 1

Finding the slope, you get [4-(-2)]/[-1-2]=6/-3 = -2

Plugging (2,-2) and -2 into the formula y=mx+b, you get that -2=-4+b.

Therefore, b=2, making the equation y = -2x+2

Answer 2

The equation is Y=-2x+2. Hope this helps
