You can put this solution on YOUR website!

The point (-4,k) and (2,1.75) lie in the graph of
+y=x%2Bb........use given point (2,1.75)
+1.75=2%2Bb......solve for b
+1.75-2=b
+b=-0.25
so far equation is
+y=x-0.25.......use given point (-4,k)
+k=-4-0.25.....solve for k
+k=-4.25

->given point (-4,k) is (-4,-4.25)

check it on a graph:
