Parallel and Perpendicular Slope Practice

If I am looking for a line parallel to $y=-3x-2$  which one of these equations could it be?

•  $y=-2x-1$  

•  $y=3x-4$  

•  $y=-3x+6$  

•  $y=-2x-3$  

 $y=\frac{-2}{3}x+2$  and  $y=\frac{3}{2}x+9$  are what kind of lines?

• Parallel

• Perpendicular

• Neither

Write the equation of a line PARALLEL to  $y=2x+3$   that passes through the point (3, 1).

• $y=2x\ -3$

• $y=2x-5$

• $y=2x\ +\ 1$

• $y=-\frac{1}{2}x+\frac{5}{2}$

Write the equation of a line PERPENDICULAR to  $y=-2x+1$  that passes through the point (2, 3).

• $y=-\frac{1}{2}x+\frac{1}{2}$

• $y=\frac{1}{2}x+2$

• $y=-2x+7$

• $y=-2x+8$

Write the equation of a line PERPENDICULAR to  $y=\frac{1}{3}x-9$  that passes through the point (-6, 10).

•  $y=\frac{1}{3}x-9$ 

•  $y=\frac{1}{3}x+10$ 

•  $y=-3x+6$ 

•  $y=-3x-8$ 

A line is perpendicular to $y=2x-7$  

What is the slope of this line? 

• -2

• 1/2

• -1/2

• 2

What slope is perpendicular to:  
m = 5/8

• -5/8
• 5/8
• -8/5
• 8/5

Two lines that are perpendicular lines have ...

• Slope that is opposite reciprocals

• No Slope

• Slope that is the same

• none of the above

Write an equation for a line parallel to the line

y = (1/3)x - 4 through (-3, 2)

• y = (2/3)x +3

• y = (-1/3)x + 3

• y = (1/3)x + 3

• y = (-5/3)x + 3

Perpendicular lines have the same slope.

• True
• False
