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 these two lines parallel, perpendicular or neither?
y = -1/3x - 5
y = 1/3x + 2

• Parallel
• Perpendicular
• Neither
