Question

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

• A. $1$
• B. $-1$
• C. $5$
• D. $-8$

Answer 1

Answer: (A)

$1$

Slope of the line passing through the points $(x_1,y_1)$ and $(x_2,y_2)$ is:

$m=\frac{y_2-y_1}{x_2-x_1}$

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

$m=\frac{3-1}{0-(-2)}=\frac{2}{2}=1$

Hence, the slope of the line is $1$.
