Question

How do you graph the function `y=3x-4`?

Answer 1

`y`-intercept is `-4`

And for every `x`-value there would be an increase of `3` in the `y` value

Explanation:

Choose `x` values and work out the `y` values.

`x rarr y`
`0, -4`
`1, -1`
`2, 2`
`3, 5`
`4, 8`
`5, 11`
`6, 14`
`7, 17`
`8, 20`
`9, 23`
`10, 26`

Now plot the points and join them with a straight line.

Whenever there's an increase in the `x` by `1`,. there will be an increase in `y` by `3.`
graph{y=3x-4 [-10, 10, -5.21, 5.21]}
