ANSWER
The ordered pair is not a solution to the equation.
Step-by-step explanation
We want to find out if (-6, -2) is a solution to the equation:
r - s = 4
Using alphabetical order for the substitution, we have that for the ordered pair:
r = -6 and s = -2
To find if it is a solution, we will substitute the value of r and 6 from the ordered pair into the equation and then, check if both sides of the equation are actually equal.
That is:
-6 - (-2) = 4
-6 + 2 = 4
-4 = 4
Since both sides of the equation are not equal, the ordered pair is not a solution to the equation.
