Linear Equation Parallel and Perpendicular

Given the line 2x-3y=9, write the equation of a line parallel to it that passes through the point (4, -1)

• y = 2/3x - 3

• y = 2/3x - 11/3

• y = 2/3x - 4

• y = 2/3x - 5/3

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

• Parallel

• Perpendicular

• Neither
