Question

Given `y=3x-4` what is the `x`-intercept?

Answer 1

`x`-int @ `x=4/3`

Explanation:

The `x`-intercept is when the graph crosses the `x`-axis, and as we know, at this axis, `y` is equal to zero. This means we can find the `x`-intercept when `y=0`:

We can set `y=0` to get

`3x-4=0`

Adding `4` to both sides, we get

`3x=4`

Lastly, dividing both sides by `3` we get

`x=4/3` as the `x`-intercept
