Slope of a Line: Introduction
You are probably familiar with a ski slope, and perhaps you’ve even been skiing yourself. The slope of the hill is a measure of the level of its incline. In geometry, we can measure the incline of lines on a plane in much the same way.
When we measure the slope of a line, we are measuring its rate of change. That is, how much the line changes vertically versus horizontally? In this section, you will learn more about the mathematical definition of slope.
