slope formula ‑ sometimes called the ʺrise over the run,ʺ this is the formula for the straight line going through the points (x1, y1) and (x2, y2) and is written as ....
slope‑intercept form ‑ the equation of a straight line in the form y = mx + b where m is the slope of the line and b is the y‑intercept
