Question

I don’t know what to do

Answer 1

A'(-7,5)

B'(-2,5)

C'(-5,8)

Explanation:

What your supposed to do is translate the triangle by the rule that it gives you.

That rule is (x,y) -> (x-2, y+4). This rule means, move 2 to the left and move 4 up.

Now, the original coordinates of the triangle are..

A(-5,1)

B(0,1)

C(-3,4)

So, subtract 2 to each x coordinate and add 4 to each y coordinate.

(-5-2, 1+4) ----> (-7,5)

(0-2, 1+4) ----> (-2,5)

(-3-2, 4+4) ----> (-5, 8)

This leaves you with the new coordinates that have been translated.

A'(-7,5)

B'(-2,5)

C'(-5,8)
