Question

Find the slope of the line passing through the following points.
(i) A($-$2,1) and B(0, 3)

Answer 1

The given points are A($-$2, 1) and B(0, 3).

Here, x₁ = $-$ 2, y₁ = 1, x₂ = 0 and y₂ = 3
$$\begin{gathered} \therefore \mathrm{Slope}\mathrm{of}\mathrm{line}\mathrm{AB}=\frac{y_2-y_1}{x_2-x_1} \\ =\frac{3-1}{0-(-2)} \\ =\frac{2}{2} \\ =1 \end{gathered}$$
