# What is the equation of the line which passes through the points (2, -3) and (1, -3)?

Mar 10, 2018

$y = - 3$

#### Explanation:

Begin by finding the slope of the line using the formula

$m = \frac{{y}_{2} - {y}_{1}}{{x}_{2} - {x}_{1}}$

For the points
$\left(2 , - 3\right) \mathmr{and} \left(1 , - 3\right)$

${x}_{1} = 2$
${x}_{2} = - 3$
${x}_{2} = 1$
${y}_{2} = - 3$

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

$m = \frac{0}{-} 1$

$m = 0$

This equation is actually a horizontal line running through the y axis at $y = - 3$
