Triangle ABC is reflected across the y-axis to form triangle A′B′C′. The coordinates of the vertices of the triangles are given below. Triangle ABC: A(2, 3) B(6, 7) C(4, 1) Triangle A′B′C′: A′(2, 3) B′(–6, 7) C′(4, 1) Make a conjecture about the coordinates of a figure and its image after a reflection across the y-axis.

answer: -10

step-by-step explanation:

s(t) = 1 - 10t

s(x) = 1 - 10x

s(x + h) = 1 - 10(x + h)

            = 1 - 10x - 10h

s(x + h) - s(x) = 1 - 10x - 10h - (1 - 10x)

                      = 1 - 10x - 10h - 1 + 10x

                      = -10h

= -10
