You cant learn about linear equations without learning about slope. Your goal is to find the change in the height of the line over the horizontal distance of the line. There are many ways to think about slope.
The slope of a line is the steepness of the line.
Calculate your rise and then your run. They are just different words none of the calculations change. The rise is the up distance and the run is the across distance shown in the above figure. The slope formula is sometimes called rise over run The simple way to think of the formula is.
