Lines Parallel and Perpendicular

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

• y = 4x + 12

• y = -4x -4

• y = -1/4x + 5/2

Select ALL of the lines that are PERPENDICULAR to y = 3/4x + 9

• y = 3/4x - 3

• y = -3/4x + 9

• y = -4/3x + 8

• 3y = -4x + 5

• 4y = -3x + 7

y = 3x +2
y = 3x - 3
These lines are...

• Parallel

• Perpendicular

• Neither

• The same line

Slopes of perpendicular lines are...

• opposite reciprocals.

• opposites.

• identical.

• always 7.
