For this case, we have to: Be an equation of the form
, 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](https://img.qammunity.org/2020/formulas/mathematics/middle-school/gfux56vhovnf5ebvf3w09ek3ftnl6y6wqy.png)
We want to know if the pair
is the solution of the equation. If we replace, we have:
![1 = 2 (2)\\1 = 4](https://img.qammunity.org/2020/formulas/mathematics/middle-school/8i3lb74jqxrlaffifxpee7zrafsfjtme9s.png)
Equality is not met, so the pair is not a solution.
Answer:
Replace the pair in the equation and see if equality is met.
