✔ x = –4y = –4x = –2y = –2

Which lines are parallel to the graph of 4x – y = 6? Check all that apply.x – 4y = –12y – 2 = –4(x + 1)y + 1 = 4(x – 2)y = 4x + 11y = x – 38x – 2y = 6

Are the lines perpendicular?

A quadrilateral has vertices E(–4, 2), F(4, 7), G(8, 1), and H(0, –4). Which statements are true? Check all that apply.The slope of EH is [image 1] .The slopes of EF and GH are both [image 2] .FG is perpendicular to GH.Quadrilateral EFGH is a parallelogram because both pairs of opposite sides are parallel.Quadrilateral EFGH is a rectangle because all angles are right angles.

For which value of a are the graphs of –4 = 3x + 6y and ax – 8y = 12 parallel?

Determine the equation of the line perpendicular to the line y = –8 through the point (–4, –2).
