Question

How do you determine whether the pair (1,8) is a solution of y= 5+3x?

Answer 1

It does lie on the line

Explanation:

To find if `(1,8)` is on the line `y=5+3x`, just substitute in `x=1` and `y=8` into the equation:
`(8)=5+3(1)`
`8=8`
Because the end result is a TRUE statement, it means that `(1,8)` is one the line
