Parallel and Perpendicular Lines and Equations

Write an equation of a line that passes through the point (5,-1) and is parallel to the line y = (-3/5)x -3

• y = (-3/5)x + 2

• y = (-3/5)x -2

• y = (3/5)x + 2

• y = (5/3) + 2

Are these lines perpendicular?
y = 4x + 2
y = (-1/4)x + 12

• YES

• NO

Write an equation of a line that passes through the point (-9,2) and is perpendicular to the line y = 3x - 12

• y = (-1/3)x - 1

• y = (1/3)x - 2

• y = -3x + 12

• y = 3x - 1

Write an equation of a line that passes through the point (7,10) and is perpendicular to the line y = (1/2)x - 9

• y = -2x - 24

• y = -2x + 12

• y = -2x  + 24

• y = (1/2)x - 12

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
