Theorems for Parallel Lines and Perpendicular Lines

Which of the following lines goes through the point        (-3, 4) and is perpendicular to  y = 3/2x + 6?

• y = 3/2x - 6

• y = 2/3x + 3

• y = -2/3x - 2

• y = -2/3x + 2

Slopes of perpendicular lines are...

• opposite reciprocals.

• opposites.

• identical.

• always 7.

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

• Parallel

• Perpendicular

• Neither

• The same line
