Equations of Perpendicular and Parallel Lines

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

Are these lines parallel?
y = 12x + 4
y = 12x +14

• YES

• NO

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

Write an equation of a line that passes through the point (2,6) and is parallel to the line y = -3

• y = 12

• y = 6

• x = 12

• x = 6

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

• YES

• NO
