Question

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

Answer 1

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

Explanation:

`y= -5/4x-3` is the equation of a straight line

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

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

With positive slopes we can use `"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)` go up 5 and left 4; plot this point.
Repeat this to get one more point, and connect the points.
