# Slope

The slope tells you how steep a line is. The larger the slope, the steeper the line.

In algebra, the slope is the “m” in the formula y = mx + b. In statistics, we’re interested in a particular kind of slope, found with the linear regression formula. In that case, the slope is the a in the equation y’ = b + ax. Here, the slope tells you what the rate of change in y (the dependent variable) is, as x (the independent variable) changes.
