Answer 3

An image point has coordinates B'(6, -8). Find the coordinates of its pre-image if the translation used was (x + 4, y - 5).
B(10, -3)
B(2, -13)
B(10, -13)
B(2, -3)

Answer 5

@Directrix

Answer 6

A(-2, 4) by (x - 2, y - 1).

x is -2 - 2 = @Melody323

and

y = 4 - 1 =

Take the x value of A and place in it for x in the formula.

Same for y value of A.

Answer 7

x = -2 - 2 =

y = 4 - 1 =

Answer 8

x = -4
y = 3

Answer 9

Thanks!

Answer 10

What about this? Do you still want to do it?

An image point has coordinates B'(6, -8).
Find the coordinates of its pre-image if the translation used was (x + 4, y - 5).

B(10, -3)
B(2, -13)
B(10, -13)
B(2, -3)
