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

• slope: 5   y-intercept:  (0,3) 

• slope: 3/2   y-intercept:  (0,3) 

• slope:  4  y-intercept:  (0,3/2)

• slope: 1/5   y-intercept:  (0,5) 

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

• A

• B

• C

• D

Write the equation 4x + 2y = -12 in slope-intercept form. 

• y =  -2x - 6

• y = 2x - 6

• y = -2x + 6

• y = 2x - 6

Find the slope of the line.

• m = 1/4

• m = -4

• m = 4

• m = - 1/4

What is the simple definition of slope? 

• line

• run/rise

• undefinied

• rise/run

Slopes of parallel lines are...

• opposite reciprocals.

• opposites.

• identical.

• always 7.
