Slopes Perpendicular and Parallel Lines

What is does the "m" stand for in this equestion?

• Y-intercept

• x-coordinate

• y-coordinate

• slope

In a coordinate plane two nonvertical lines are (blank) if the product of their slopes are -1

What is the equation for the yellow line? (assume both lines are parallel)

• y=1/2x+6

• y=2x-6

• y=2x+6

• y=1/2x-6

The lines through the given points are...

• parallel

• perpendicular

• neither

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

• Parallel

• Perpendicular

• Neither

• The same line

y = -2/3x + 2
y = 3/2x + 9
These lines are...

• Parallel

• Perpendicular

• Neither

Match the following to its perpendicular slope

• 5/7

• 5/4

• -4/5

• -2/3

• -4/15

• -7/5

• 3/2

• 15/4

Are these two lines parallel, perpendicular or neither?
y = -1/3x - 5
y = 1/3x + 2

• Parallel

• Perpendicular

• Neither

The two lines are _____________________.

• Parallel

• Perpendicular

• Neither

Two lines are parallel if they have the same??
