Answer:

The answer is A.

Explanation:

In order to see if a coordinate is a solution to any equation, you have to substitute the values of x and y into the equation :


- 3x + 2y = - 21


let \: x = 5 \\ let \: y = - 3


- 3(5) + 2( - 3) = - 15 - 6 = - 21

AND


- x - y = - 2


let \: x = 5 \\ let \: y = - 3


- 5 - ( - 3) = - 5 + 3 = - 2
