The Slope of a Line

Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

$\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

The graph provided suggests the use of the points (3,-3) and (5,-3). The slope is:

$\displaystyle m=\frac{-3+3}{5-3}=\frac{0}{2}=0$

The slope of the line is 0. It corresponds to a horizontal line
