Question

consider the figure shown on the graph.Which equation represents the line of reflection that maps ABC onto EDF?

Answer 1

Let's begin by listing out the information given:

A (-1, 0); B (-3, 0); C (-1, 3)

E (2, -3); D (2, -5); F (5, -3)

A = E; B = D; C = F

A (-1, 0) = E (2, -3) = (2--1, -3-0) = (3, -3)

B (-3, 0) = D (2, -5) = (2--3, -5-0) = (5, -5)

C (-1, 3) = F (5, -3) = (5--1, -3-3) = (6, -6)

We observe that x = -y or y = -x

$y=-x$
