Question

Given Triangle ABC has vertices A(2,-3), B(5,-4) and C(2,1). What will be the vertices of Triangle A’B’C’ when Triangle ABC is reflected over the x-axis? What are the new image points ?

Answer 1

"reflected over the x axis" means that the x coordinates are the same magnitude, but with the opposite sign. So, if a point was (-4,6), the new point would be (4,6)

The y values will not be affected

"reflected over the y axis" is the same thing, except that the y values are now affected, and the x values stay the same.
