Question

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

Answer 1

Given points are $A(-2,1)$ and $B(0,3)$
$\Rightarrow A=(x_1,y_1)=(-2,1),B=(x_2,y_2)=(0,3)$
$\therefore$ Slope of the line $AB=\frac{y_2-y_1}{x_2-x_1}$
$=\frac{3-1}{0-(-2)}$
$=\frac{2}{2}=1$
Hence, the slope of the given line is $1$.
