Perpendicular and Parallel Lines

What slope is perpendicular to:

m = -3

• -3

• -1/3

• 1/3

• 3

Select all that are true.

• Parallel lines never intersect.

• Parallel lines intersect at a right angle.

• Perpendicular lines never intersect.

• Perpendicular lines intersect at a right angle.

Write an equation that is parallel to
y = -2x + 4
and runs through the point (-3, 2 )

• y = - 2x - 4

• y = - 2x - 8

• y = - 2x + 4

Are these lines parallel, perpendicular, or just intersecting (but not perpendicular)?

• Parallel

• Perpendicular

• Intersecting (but not perpendicular)
