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=(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=(-3+3)/(5-3)=(0)/(2)=0

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