Answer:
The sign of each y-coordinate changed.
Step-by-step explanation:
This was a reflection over the x-axis.
If you look at point F, it is (-5, -1) the corresponding point F' is (-5,1). Notice the numerical values of x and y are the same, but the sign of y flipped from negative to positive. The other four points all follow the same pattern.
Step-by-step explanation:
y -4x = -1
y = 4x -1
then y = Mx + b
m = 4
b = -1
4x + 10 = -26
-10 -10
4x = -36
Then -36 divided by 4
X= -9 -9 is the answer.
