LF be a linear function that is increasing and goes through the point (-2,-3)?

Question

B) find F(4)
C) find x when F(x)=4

Answer 1

The equation will have the form y+3 =m(x+2) where m>0

So y=mx+2m-3
B)
f(4) = 4m+2m-3=2(3m-1)

C)
Require
4=mx+2m-3 leads to x=(7-2m)/m

Answer 2

There are an infinite number of increasing linear functions that pass through (-2,-3). Which one are you asking about?
