calculatedThe slope between any two points can be calculated by dividing the change in y by the respective change in x value.
[tex]\text{slope = }\frac{\text{change in y}}{\text{change in x}}[/tex][tex]\begin{gathered} \text{Suppose the two points are given to be points (x}_1,y_1)and(x_2,y_2) \\ \text{Then the slope will be }\frac{y_2-y_1}{x_2-x_1} \end{gathered}[/tex]
Example
To calculate the slope of the line joining the points (1,2) and (3,4):
[tex]\begin{gathered} x_1=1,y_1=2 \\ x_2=3,y_2=4 \\ \text{Slope = }\frac{4-2}{3-1} \\ \text{slope = }\frac{2}{2} \\ \text{slope = 1} \end{gathered}[/tex]
