Question

How do you find the x and y intercepts for `4x+y=8`?

Answer 1

Calculate f(0) and y = 0

Explanation:

Let's start with interception point with the x axis. Here we know that `y = 0`, so we can put that in our original expression:

`4x + 0 = 8`
`4x = 8`
`x = 2`

The function intercepts the x axis at `(2, 0)`

Let's continue with the y axis. Here we know that `x = 0`, so let's put that into our expression / function:

`4*0 + y = 8`
`y = 8`

This gives us interception point with y axis at: `(0, 8)`
