Question

Identify which lines are perpendicular.
y = - 1/5 x + 2.
y = - 4.
y- 6 = 5 (x+4)
and y = 3x + 3

Answer 1

Perpendicular lines have slopes that multiply to -1 with the exception of a vertical and horizontal line. In this question, do you want to know which line or lines are perpendicular to y = -1/5 x + 2? Or, of the four lines, do you want to know which pairs are perpendicular?

Answer 2

lines
