Question

Can someone help me with this question?

Trapezoid TUVW is shown on the coordinate plane below:

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.)

I think that it's 6,2

Answer 1

(-5, 6) would have to be the correct answer! 

Answer 2

The reflection over the y-axis has a rule:

`(x,y)\rightarrow (-x,y).`

From the diagram you can see that point W has coordinates (-7,2). Then using the rule given above, you can find the coordinates of point W':

`(-7,2)\rightarrow (7,2).`

Answer: (7,2).
