Work Step by Step

The slope of a line is the change in the value of $y$ for each unit increase in $x$. Slope can also be interpreted as a measure of steepness of a line. A positive slope means the value of y is increasing from left to right, while a negative slope means the value of y is decreasing from left to right.
