# How do you find the slope of the line passing through the points (–4, 3) and (10, 3)?

slope is zero.

#### Explanation:

Use the slope formula: $m = \frac{{y}_{2} - {y}_{1}}{{x}_{2} - {x}_{1}}$

$m = \frac{3 - 3}{10 - - 4} = \frac{0}{14} = 0$

A quicker way is to recognize that the y-coordinate is the same in each point. This means the line must be a horizontal line. All horizontal lines have a slope of 0.

slope m=0

#### Explanation:

we know the slope of a line passing through two points ( ${x}_{1} , {y}_{1}$) and ( ${x}_{2} , {y}_{2}$) is
m= ${y}_{2} - {y}_{1} / {x}_{2} - {x}_{1}$

so
m= $3 - 3 / 10 - \left(- 4\right)$
m=0/14
m=0

$\tan \left(\theta\right)$=0
