# What is the slope of the line passing through the following points: (17,11) , (21,19) ?

2

#### Explanation:

Slope is change in y over change in x. Change in y is 19-11, or 8, and change in x is 21-17, or 4. You would get $\frac{8}{4}$, or just simply 2.

$\text{slope } = 2$

#### Explanation:

$\text{to calculate the slope m use the "color(blue)"gradient formula}$

•color(white)(x)m=(y_2-y_1)/(x_2-x_1)

$\text{let "(x_1,y_1)=(17,11)" and } \left({x}_{2} , {y}_{2}\right) = \left(21 , 19\right)$

$\Rightarrow m = \frac{19 - 11}{21 - 17} = \frac{8}{4} = 2$
