## Point Slope Form: How to Use Rise Over Run

Today, we’re going to look at slope — the grade of a straight line on the coordinate plane. Specifically, we’re looking at how to use the rise over run formula to measure a line’s slope. This is sometimes also called the “slope formula,” which states that slope = (change in y)/(change in x), or (y1 […]
