Answer:
y+1=-1/2(x-2) OR y-1=-1/2(x+2)
Step-by-step explanation:
1) First lets find the slope:
(1--1)/(-2-2)
2) Solve
2/-4
3) Simplify:
-1/2
4) Now lets put one set of points, and our slope into the point slope formula:
y+1=-1/2(x-2)
5) Now lets put the other set of points and the slope into the form:
y-1=-1/2(x+2)
