If figure abc is reflected across the line x = –3 to create figure a'b'c', which of the following will not be a vertex of figure a'b'c'? a(-5,5) b(-2,1) c(-6,-2) choices: a. (–4, 1) b. (–2, –7) c. (–1, 5) d. (0, –2)

The answer to this question would be: B.(–2, –7)

When doing reflection with x=-3 the Y coordinate of the each point wouldn't have changed. The Y coordinate of point A=5, B=1 and C=-2. No coordinate have Y value of -7 as the point B option. The result of the reflection would be paired like this: 

B(-2,1) = (–4, 1) 
A(-5,5) = (–1, 5)
C(-6,-2) = (0, –2)
