# y = -3x - 5 What is the slope? What is the y-intercept?

Dec 5, 2017

$\text{slope "=-3" and y-intercept } = - 5$

#### Explanation:

$\text{the equation of a line in "color(blue)"slope-intercept form }$ is.

$\textcolor{red}{\overline{\underline{| \textcolor{w h i t e}{\frac{2}{2}} \textcolor{b l a c k}{y = m x + b} \textcolor{w h i t e}{\frac{2}{2}} |}}}$

$\text{where m is the slope and b the y-intercept}$

$y = - 3 x - 5 \text{ is in this form}$

$\Rightarrow \text{slope "=m=-3" and y-intercept } = b = - 5$

The slope is $- 3$ and the $y$-intercept is $- 5$.

#### Explanation:

The equation is in slope-intercept form

$y = m x + b$

where $m$ is the slope, $x$ is the $x$ value, and $m$ is the $y$-intercept. The number before the $x$ variable is the slope, so $- 3$. The number added is $\left(- 5\right)$, so $5$ is subtracted or $\left(- 5\right)$ is added.
