# Find the slope of a line parallel to the line that crosses (1,3) and the y-intercept is (0,-4), m =?

Dec 9, 2017

The slope is $7$.

#### Explanation:

Parallel lines have the same slope, so we can use the slope formula here with the given points:

$\setminus \frac{{y}_{2} - {y}_{1}}{{x}_{2} - {x}_{1}}$

$\setminus \implies \setminus \frac{- 4 - 3}{0 - 1}$

$\setminus \implies \setminus \frac{- 7}{- 1}$

$\setminus \implies 7$
