Answer:
slope [tex]=\frac{y_{2} -y_{1} }{x_2-x_1}[/tex]
Explanation:
the slope of a graph in general is the following
slope [tex]=\frac{y_{2} -y_{1} }{x_2-x_1}[/tex] (1)
1) Pick two points on the graph
2) The coordinate of the first point is[tex](x_1,y_1)[/tex], while the second point is [tex](x_2,y_2)[/tex].
3) Substitute with the coordinate values in equation (1) to get the slope
