Writing Equations of Parallel and Perpendicular Lines

Which of the following equations represents the line passing through point A and PERPENDICULAR to the given line?

• -2x + 3y = 10

• 2x + y = 6

• 3x + 2y = -4

• -3x - 2y = 2

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).

Are the two linear equations parallel, perpendicular, or neither?

• Parallel

• Perpendicular

• Neither
