Question

Point A(1,3) is reflected across the x-axis to create Point A’. The line y=2x-5 pass through point A’

True or False?

Answer 1

True

Explanation:

Best to use a graphing calculator or graph it onto paper, after you change Point A after it reflected over the x - axis. The rule for reflection over the x-axis is (x, y) ---> (x, -y), so all you would need to do is change the positive 3 (the y value of A) into -3. So A' = (1, -3)
