Question

What are the coordinates of the pre-image of M' if it was reflected across the y-axis, and M' has coordinates (3, -2)?

Answer 1

the two points are the same distance, so they are the same number, but they may or may not be negative. I will draw a pic. for you so maybe you can understand

Answer 2

based from this, what would the x and y variables be?

Answer 3

-3, 2?

Answer 4

it would be (-3, -2) because the y variable stays the same when reflected over the y-axis, just as the x variable stays the same when reflected over the x-axis

Answer 5

Oh, I see now.

Answer 6

yes does that make sense?
