40 POINTS! BRAINLIEST!
Sorry I was missing info on the last question:

ABC is the red triangle.
A(-2, 1) B(-2, 4) C(1, 1)

DEF is the purple triangle.
D(4, 2) E(4, 4) F(6, 2)

Triangle ABC is similar to DEF. Write the equation, in slope-intercept form, of the side of triangle DEF that is parallel to BC.
