Answer with explanation:
→Suppose ,y= mx +c, is a linear equation and the line passes through two points ,[tex](x_{1},y_{1}),(x_{2},y_{2})[/tex].
→Slope of line joining two points having coordinates ,[tex](x_{1},y_{1}),(x_{2},y_{2})[/tex] can be obtained by the formula
[tex]m=\frac{\text{Difference of y coordinates}}{\text{Difference of x coordinates}}\\\\m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
