Finding Equations of Parallel and Perpendicular Lines

Write the equation of a line PARALLEL to y = 2x + 3 that passes through the point (3, 1).

Write the equation of a line PERPENDICULAR to y = -2x + 1 that passes through the point (2, 3).

Write the equation of a line PARALLEL to 3x - y = 2 that passes through the point (1, 5).

• y = 3x - 14

• y = 3x + 2

Are the equations parallel, perpendicular, or neither?

• Parallel

• Perpendicular

• Neither

Mabel graphed the equations y = (1/3)x + 2 and y = 3x + 2.

These lines are​ ​ (a)   because their slopes are ​ (b)   .

• perpendicular

• intersecting at an angle that is not 90 degrees

• parallel

• reciprocals, but are not opposites

• equal

• opposites, but not reciprocals
