Question

Find the slope of the line that passes through the points $(-1,0)$ and $(3,8)$

• A. 1
• B. -1
• C. 2
• D. 3

Answer 1

The correct option is C 2

Since slope of line passing through two points $(x_1,y_1)$ and $(x_2,y_2)$ is $m=\frac{y_2-y_1}{x_2-x_1}$

We now find the slope of the line passing through the points $(-1,0)$ and $(3,8)$ as shown below:

$m=\frac{8-0}{3-(-1)}=\frac{8}{4}=2$

Therefore, the slope of the line is $2$.
