Question

Find the slope of the line passing through the points $A(2,3)$ and $B(4,7)$.

Answer 1

Fact: Slope of line passing through the points $(x_1,y_1)$ and $(x_2,y_2)$ is given by, $m=\frac{y_2-y_1}{x_2-x_1}$

Therefore slope of line passing through the points $A(2,3)$ and $B(4,7)$ is $=\frac{7-3}{4-2}=\frac{4}{2}=2$
