Question #97270

Answer 1

Equation is already in `y=mx+b` format. Just graph using the slope and y-intercept.

Explanation:

So the equation (`y=9/4x-4`) is already in `y=mx+b` format.
=> Where `9/4` is the slope, `m`.
=> Where `-4` is the y-intercept, `b`.

All we have to do is graph it.

graph{9/4x-4 [-10, 10, -5, 5]}

I think what you have difficulty with, is the slope. You can use the `"rise"/"run"` method to graph the slope.

Basically, all numerators are `"rise"`, and all denominators are `"run"`. So in this case, starting at `(0, -4)`, move up `9` points, then right `4` points, giving us `(4, 5)`.

You also do the opposite: starting at `(0, -4)`, move down `9` points, then left `4` points, giving us `(-4, -13)`.

Connect them with a straight line and BAM!

Hope this helps :)
