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 [math]y=mx+b[/math] where [math]m[/math] is the slope (rise divided by run) and [math]b[/math] is the y-intercept.

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