# How do you find the slope and intercept of y= -5x-4?

$\text{slope "=-5," y-intercept } = - 4$

#### Explanation:

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

•color(white)(x)y=mx+b

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

$y = - 5 x - 4 \text{ is in this form}$

$\text{with slope "=-5" and y-intercept } = - 4$

Slope = -5/1
Y-intercept = -4

#### Explanation:

The y-intercept is -4 because it is not in front of an x in the problem. It stands alone at the end and tells you to start at (0,-4).

The slope of the equation is in from of the x in the equation, therefore the slope is -5/1.

Another way to think of this is left 1 then up 5.

As you can see on the graph I added, the line crosses the Y axis at -4, then the line follows negatively by moving to the left 1 (because its negative) then up 5.
