Question

If trapezoid T'U'V'W' represents trapezoid TUVW reflected over the y-axis, the ordered pair of W' is ___________. (Note: You must include parentheses, a comma, and a space after the comma when typing the ordered pair.)

Answer 1

I think it's (6, -4)

Answer 2

Ok so when it says "reflected over the y-axis, first let me ask you what do you think this means? What value is given to y when referring to the (y)-axis here?

Answer 3

Go ahead and tell me what ordered pair represents the coordinate (W') first.

Answer 4

(-6, -4)

Answer 5

Since it is reflected over the y-axis, we must keep x the same.

Answer 6

So it will be (-6, Something)

Answer 7

And since it is a reflection, we take the opposite y.

Reflection across the y axis will be (x, y) reflects to (x, -y)

Answer 8

So if W' is (-6, -4), we should get (-6, 4) as the point reflected over the y=0, or y-axis

Answer 9

You were correct, I just wanted you to see why =0)

Answer 10

Yay thank you! :)

Answer 11

Reflection across x is (x, y) -> (-x, y)
Reflection across the Origin is (x, y) -> (-x, -y) as well!
