Question

triangle pqr is reflected over a vertical line of reflection to create triangle pqr. what are the coordinates of point q? (1 point) (-3,1) (12,7) (7,-2) (-2,7)

Explanation:

Step1: Find reflection line using P and P'

Midpoint x: $(-8 + (-6))/2 = -7$, so line $x=-7$.

Step2: Calculate Q' coordinates

For Q(-12,7), $x' = 2*(-7) - (-12) = -2$, $y'=7$. Thus Q'(-2,7).

Answer:

(-2,7)
