Question

9) Find the equation of a mirror line to the points Q (1,2) and Q1 (-1,2)

​

Answer 1

x = 0

Explanation:

Q(1, 2 ) and Q1(- 1, 2 ) are both 1 unit from the y- axis

Q is 1 unit to the right of the y- axis and Q1 is 1 unit is 1 unit to the left of the y-axis, thus

The y- axis is the mirror line with equation x = 0
