Linear Functions Review

Write an equation of the line in slope-intercept form:

•  $y=\frac{3}{2}x-3$  

•  $y=6x+3$  

•  $y=\frac{3}{2}x+3$  

•  $y=4x-3$  

.Use the graph to determine the equation of the line in slope-intercept form.

• y = 3x + 3

• y = 1/3x + 3

• y = -1/3x +3

• y = - 3x + 3

What is the y-intercept of this line?

• -3

• -2

• 0

Which is the graph of y= -x + 2?

• A
• B
• C
• D

Find the slope of the line.

• 1/2
• -1/2
• 2
• -2

If the graph of the parent function f(x) = x is shifted 7 units
down, which of the following equations would the new graphed
line represent?

• f(x) = 7x
• f(x) = x - 7
• f(x) = x + 7
• f(x) = 7x - 7

Describe the transformation from the parent function: y = 3x + 5
