Find the slope of the function, when points A(1,3) and B(7,12) belongs to this function?

Any ideas? Maybe is it special formula for finding slope?

If we have two points of the straight line function, we can use this formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] to find the slope of this line. So there we have: $$\text{Slope}=\frac{y_2-y_1}{x_2-x_1}=\frac{12-3}{7-1}=\frac{9}{8}=1\frac{1}{8}$$
