How to Find Slope: Rise Over Run
Find the slope between two points by counting rise over run. A comic courier travels from (1, 2) to (4, 8), so the rise is 6, the run is 3, and the slope is 2. Connect the graph to the slope formula.

Transcript
0:01 A comic courier moves from point one, two to point four, eight.
0:06 Count the horizontal run: three steps to the right.
0:11 Now count the vertical rise: six steps up.
0:16 Slope means rise divided by run. Six divided by three equals two.
0:22 For every one step right, this line climbs two steps.
0:28 The formula says eight minus two, divided by four minus one.
0:33 That is six over three. Keep the coordinate subtraction in the same order.
0:41 Slope is the change in y for each one-unit change in x.
