Answer:
BGC
Step-by-step explanation:
im pretty aure aorry if u get it wrong man
Y=-2 is a horizontal straight line. The perpendicular line is going to be a vertical line (x=). Since it is vertical with no range, the line is a y-output of all numbers at any x input. So for the line to get to (4, -2) the x would need to be at 4, making the perpendicular line x=4
Scale Factor=4
I just counted how many units GF was and I came out with 5. Then I looked at the length of G’F’ and saw that it was at 20 units. 20/5=4
10 - x is the answer.
x represents the unknown number.
Hope this helps!
