Parallel and Perpendicular Lines

What slope is parallel to:  
m = 3/4

• 4/3
• 3/4
• -3/4
• -4/3

What slope is perpendicular to:  
m = 5/8

• -5/8
• 5/8
• -8/5
• 8/5

y = 5/7x +2
y = 5/7x - 30
These lines are...

• Parallel
• Perpendicular
• Neither

y = 6x + 2
y = -6x + 2
These lines are...

Given the line 2x-3y=9, write the equation of a line parallel to it that passes through the point (4, -1)

• y = 2/3x - 3
• y = 2/3x - 11/3
• y = 2/3x - 4
• y = 2/3x - 5/3

Line m contains the points (-3, 4) and (1, 0). Write the equation of a line that would be parallel to this one, and pass through the point (-2, 6).

• y = -x + 4
• y = x + 6
• y = 3x - 5
• y = 2x 

Slopes of parallel lines are...

• opposite reciprocals.
• opposites.
• identical.
• always 7.

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

-6x + y = 2
6x + y = 2
These lines are...

• Parallel
• Perpendicular
• Neither
