HELP ME PLEASE PLEASE

Answer 1

Answer:

The answer is A.

Step-by-step 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

$- x - y = - 2$

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

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