Discovering Slope Using Similar Right Triangles

“Slope is defined as the comparison between two numbers: the vertical length to the horizontal length or it is also known as the difference in the y values versus the difference in the x values.” ... x1 = x2. y1. m. y2. x1 = x2. y1. y2 - x2 - m = y1. x1. y1 - m = y2. x1 - X2.
