Question

Y=4x−9
Complete the missing value in the solution to the equation

Answer 1

The missing value is 3, and the coordinates are (3,3).

Explanation:

The complete question is

`y=4x-9`

Complete the missing value in the solution to the equation. (3, ? )

By given, we know that
`x=3`, because coordinates are written like
`(x,y)`.

Then, we replace the given coordinate to find
`y`.

`y=4x-9\\y=4(3)-9\\y=12-9\\y=3`

Therefore, the missing value is 3, and the coordinates are (3,3).
