Question

How do you graph `y=-1/4x-5`?

Answer 1

Method below

Explanation:

First, we find the `y`-intercept by substituting `x=0`:
`y=-1/4(0)-5`
`y=-5`, so the y intercept is `(0,-5)`

Then we find the `x`-intercept by substituting `y=0`:
`0=-1/4x-5`
`1/4x=-5`
`x=-20`, so the x intercept is `(-20,0)`

Now what we know two points, we just plot them on the graph and draw a line connecting them and extending past them

graph{y=-1/4x-5 [-31.6, 27.07, -13.28, 16.06]}
