Question

How do you find slope and intercepts to graph `y=4x+9`?

Answer 1

Slope: `4`
Y-intercept: `9`
X-intercept: `-2.25` or `(-9/4)`

Explanation:

`y=4x+9` is in the form `y=mx+b`, so the slope (`m`) is `4` and the Y-intercept (`b`) is `9`.
To find the X-intercept, set `y` to `0`.
`0=4x+9` Subtract `9` from each side
`4x=-9` Divide by `4`
`x=-9/4` or `x=-2.25`
