Finding the slope of a line is a fundamental skill for every user of mathematics.

Sometimes you need to find the slope of a line based on two given points. Sometimes you need to read a linear equation and determine the slope of a lone from the equation. This solution covers both of these cases and shows how to avoid errors, especially when determining the slope from two points. It also shows how to interpr
