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

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

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

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

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

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

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