If the slope of a line is 3, what does it mean in terms of rise and run?

• It means that for every 3 unit decrease in the x-axis (run), there is a 1 unit increase in the y-axis (rise).

• It means that for every 1 unit increase in the x-axis (run), there is a 1 unit increase in the y-axis (rise).

• It means that for every 3 unit increase in the x-axis (run), there is a 1 unit increase in the y-axis (rise).

• It means that for every 1 unit increase in the x-axis (run), there is a 3 unit increase in the y-axis (rise).

All of the following statements about slope are true EXCEPT:

• Slope measures the steepness of a line.

• Slope is the change in y over the change in x.

• There are only two different types of slope. Positive (uphill) and Negative (downhill).

When you graph a line using slope-intercept form, you plot the  ___________ first and then use the ___________ to get another point on the line.

• origin; slope 

• slope; y-intercept

• y-intercept; x-intercept

• y-intercept; slope

How do you rewrite an equation in SLOPE-INTERCEPT FORM?

• Solve the equation for y

• Graph the equation

• Nothing. All equations are already in slope-intercept form

• Make a table of values
