Which two transformations are applied to pentagon ABCDE to create A'B'C'D'E'? (4 points)

a
Translated according to the rule (x, y) →(x + 8, y + 2) and reflected across the y-axis

b
Translated according to the rule (x, y) →(x + 2, y + 8) and reflected across the x-axis

c
Translated according to the rule (x, y) →(x + 2, y + 8) and reflected across the y-axis

d
Translated according to the rule (x, y) →(x + 8, y + 2) and reflected across the x-axis

Answer 1

any attempts to apply any of these transformations and see if they take you from ABCDE to A'B'C'D'E'?

for example, to test choice a, Translated according to the rule (x, y) →(x + 8, y + 2) and reflected across the y-axis ----> start with ABCDE, add 8 to the x-coordinates, add 2 to the y-coordinates, and reflect across the y-axis (to reflect across the y-axis, multiply all the y-coordinates by -1), and see if it gets you from ABCDE to A'B'C'D'E'
