By plotting the points we can visualize what the slope means. Calculate the slope from 2 points. Step TwoSelect one to be x1 y1 and the other to be x2 y2.
Plug the given values into the formula for a slope.
If 1 Point and the Slope are Known. The slope of a line passing through two points P x 1 y 1 and Q x 2 y 2 is given by m y 2 y 1 x 2 x 1. This analytical method is used since it is a plane and not a slope just the two sets of X and Y coordinates x1 y1 and x2 y2 are enough to calculate the equation of the straight line. In this video I show how to calculate slope using the slope formula and why it works.
