Find the slope of a line perpendicular to the line below
y = ½x + 4

The following represents slopes of two lines.  Which answer choice describes the two lines?
m = 3/4 and m = 4/3
Parallel, Perpendicular, or Neither

Use slope to determine if lines AB and CD are parallel, perpendicular, or neither.

A(5, -8), B(-2, -10), C(-6, -13), D(-2, 1)

Write an equation of a line that passes through the point (-9,2) and is perpendicular to the line y = 3x - 12

• y = (-1/3)x - 1
• y = (1/3)x - 2
• y = -3x + 12
• y = 3x - 1

What is the equation of a line parallel to the following line that passes through the given point? 
y = -4x + 6      (2, -1)

• y = 1/4x + 6
• y = -4x + 7
• y = -4x + 2
• y = 1/4x -1 

What slope is perpendicular to:  
m = 5/8

• -5/8
• 5/8
• -8/5
• 8/5

Determine the slope and y-intercept from the following equation:   2y = 3x + 6

• m: 2/3   b:  (0,3) 
• m: 3/2   b:  (0,3) 
• m:  4  b:  (0,3/2)
• m: 1/5   b:  (0,5) 

Use the equations given to determine if the following lines are parallel, perpendicular, neither or both.
y=4x-2
y-3=-1/4(x-8)

• parallel
• perpendicular
• neither parallel nor perpendicular
• both parallel and perpendicular
