Question

How do you determine if an ordered pair is a solution to a given equation?

Answer 1

You have to substitute the x-value into the equation to see whether the solution gives the y-value.

Explanation:

Answer 2

For this case, we have to: Be an equation of the form
`y = f (x)`, where f (x) represents an expression as a function of the variable "x". To determine if an ordered pair is a solution to that equation, you must replace the pair in the equation and see if equality is met.

Example:

Let
`y = 2x`

We want to know if the pair
`(x, y) = (2,1)` is the solution of the equation. If we replace, we have:

`1 = 2 (2)\\1 = 4`

Equality is not met, so the pair is not a solution.

Answer:

Replace the pair in the equation and see if equality is met.
