Revolt · Accepted Answer

x + 2y = 8

Question 4

On a coordinate plane, a line goes through (negative 3, 3) and (negative 2, 1). A point is at (4, 1).

Revolt · Accepted Answer

y − 1 = −2(x − 4)

Question 5

On a coordinate plane, 2 lines are shown. Line P Q has points (negative 5, 3) and (5, 1). Line R S has points (negative 4, negative 2) and (0, negative 4).

Revolt · Accepted Answer

They are not parallel because their slopes are not equal.
