Question

Triangle XYZ is shown on the coordinate plane below. If triangle XYZ is reflected across the line y = 1 to create triangle X’Y’Z’, select the location on the graph where X’ lies.

Answer 1

what is the y coordinate of point X

Answer 2

5

Answer 3

how far is that from the line y = 1

Answer 4

4?

Answer 5

so because it's 4 units away, you just start at the point (4,1) and you move 4 units down to get to the point (4, -3)

this is because when you reflect X to get X', both points will be 4 units away from y = 1
