Question

Point A (-2, -10) is reflected over the x-axis. Write the coordinates of A'. (a) (2,-10) (b) (2,10) (c) (-2,-10) (d) (-2,10)

Answer 1

Given:

Point is (-2,-10)

If the reflect about x axis then the value of x is constant and value of y change sign.

then:

So the reflected point is (-2,10)
