# How do you graph y=-5/4x-3?

graph{-5/4x - 3 [-10, 10, -5, 5]}

#### Explanation:

$y = - \frac{5}{4} x - 3$ is the equation of a straight line

and it is already in slope-intercept form, $y = m x + c$.

Lets start with the y intercept. this is the $- 3$.
So we plot a point at $\left(0 , - 3\right) .$

With positive slopes we can use $\text{rise"/"run}$ or up and right.

BUT we have a negative slope so we will go up and left.

Starting from our y intercept, $\left(0 , - 3\right)$ go up 5 and left 4; plot this point.
Repeat this to get one more point, and connect the points.
