Question

How do you find three solutions of the equation `y=9x-4`?

Answer 1

See the solution process below:

Explanation:

To find three solutions to this equation, substitute three different numbers and calculate the result for `y`:

1) Set `x = 0`

`y = 9x - 4` becomes:

`y = (9 * 0) - 4`

`y = 9 - 4`

`y = 5`

The first solution is: `(0, 5)`

2) Set `x = 10`

`y = 9x - 4` becomes:

`y = (9 * 10) - 4`

`y = 90 - 4`

`y = 86`

The second solution is: `(10, 86)`

3) Set `x = -10`

`y = 9x - 4` becomes:

`y = (9 * -10) - 4`

`y = -90 - 4`

`y = -94`

The third solution is: `(-10, -94)`
