Question

How can you tell if an ordered pair (x,y) is a solution or a system of linear equations?

Answer 1

To figure out if an ordered pair is a solution to an equation, you could perform a test. Identify the x-value in the ordered pair and plug it into the equation. When you simplify, if the y-value you get is the same as the y-value in the ordered pair, then that ordered pair is indeed a solution to the equation.

Answer 2

you will know because it you do the system of whatever thingy and there are no two dots in the same row and the line is straight in either a negative or positive slope at a diagonal the equation is linear and its a function.

Explanation:

The image is an example of a linear equation that is both a function and positive lenear
