Parallel and Perpendicular Lines

Write the equation of the line PARALLEL to the line y = 4x - 9 that passes through the point (-2, 4)

Write the equation of a line PERPENDICULAR to the line y = 3x + 2 that passes through the point (9, -2)

• y = -1/3x - 5

• y = 3x-29

• y = 1/3x -5

• y = -1/3x +1

Write the equation of a line in slope intercept form that is perpendicular to

y = (2/3)x - 4 and passes through (-6, 1).

Write the equation of a line in slope intercept form that is parallel to

y = -4x + 1 and passes through (-1/2, 2)?

y = 6x + 2
