Print Test (Only the test content will print)

## Slope-Intercept Form: Finding Slope

Instructions: A linear equation can be expressed in different ways, but one of the most useful forms is slope-intercept form. Slope-intercept form is expressed as $y=mx+b$ where $m$ is the slope (rise divided by run) and $b$ is the y-intercept.

Find the slope of each line using slope-intercept form. Watch out! You may need to rewrite some equations into $y=mx+b$ form before finding the slope.
