U can talk only for 11 minutes and have 2cents left
F(0)= -4(0)+9
F(0)= 0+9
F(0)=9
(x-3.2, y+1) . Y'=(4.3, 6) Z'=(4.8, 5)
The preimage (6,-2.3) differs from the image (2.8,-1.3) by subtracting the coordinates of the pre-image from the image leaving a -3.2 difference for x and a +1 for the y value. apply this rule to Y and Z to get Y' and Z'.
