Your goal is to find the change in the height of the line over the horizontal distance of the line. You cant learn about linear equations without learning about slope. Runinches Rise tanangle Roof Pitch Rise Run 12 Slope Rise Run 100 Example.
M stands for slope.
To find slope divide rise by run and multiply it by 100 and for angle take tan -1 of SN. If playback doesnt begin shortly try restarting your device. Just like we saw before rise over run slope. Find two nice points.
