An ordered pair is a value of x paired with a value for y. An ordered pair is a member of the solution set of an equation if and only if the replacement of x and y in the equations by the values given in the ordered pair make the equation a true statement. An ordered pair is a member of the solution set of a system of two equations in two variables if and only if the values for x and y make both of the equations true statements.
(-2,15) is the given ordered pair. is the x-coordinate value, and is the y-coordinate value. We know that because they are always in that order, hence the term 'ordered pair.'
: Replace x and y with the given coordinate values:
Is a true statement?
: Replace x and y with the given coordinate values:
Is a true statement?
If the answer to both questions is YES, then the given ordered pair is a member of the solution set.
If the answer to either or both questions is NO, then the given ordered pair is NOT a member of the solution set.
I'll leave it to you to do the arithmetic and decide.
