Question

LESSON 2 | SESSION 2 pply It Use what you learned to solve these problems. Seth reflects ABC across the x-axis to form DEF. Draw DEF. What are the coordinates of the vertices of ADEF? АУ 2 х -4 -2 O 2 4 B А -2 C

Answer 1

step 1

Remember that the rule of the reflection across the x-axis is equal to

(x,y) -------> (x,-y)

we have the coordinates

A(1,-2)

B(3,-2)

C(3,-4)

step 2

apply the rule

A(1,-2) ------> D(1,2)

B(3,-2) -----> E(3,2)

C(3,-4) ----> F(3,4)

step 3

Draw the figure

using a graphing tool

see the attached figure
