How do you interpret the slope of the straight line graph?

The slope of a straight line graph represents the rate of change between the two variables plotted on the axes. Specifically, it indicates how much the dependent variable changes for a one-unit increase in the independent variable. A positive slope signifies a direct relationship, where increases in the independent variable lead to increases in the dependent variable, while a negative slope indicates an inverse relationship. The steeper the slope, the greater the rate of change.
