Question

Find the slope of the line joining the points (3, -2)and (-1,4)

Answer 1

Slope of the line joining $\left(x_1{y}_1\right)$ and $\left(x_2{y}_2\right)=\frac{y_1-y_2}{x_1-x_2}$

$\therefore$ Slope of the line joining $(3,-2)$ and $(-1,4)=\frac{-2-4}{3-(-1)}$

$=\frac{-6}{4}$

$\frac{-3}{2}$
