Answer by Annabelle1(69) (Show Source): You can put this solution on YOUR website! a linear graph has the form y=mx+b
f(2)=-3 means that when x=2, y=-3
so wehave -3=2m+b
f(-2)=5 means that when x=-2, y=5
so we have 5=-2m+b
we solve these simulateously
Solve: We'll use substitution. After moving 1*b to the right, we get: , or . Substitute that
into another equation: and simplify: So, we know that b=1. Since , m=-2.
