Step-by-step explanation:

you only need to put the cans fire x and y into the equation and see, if the equation is still true.

for (7, -3) :

3×7 - 5×-3 = -13

21 + 15 = -13

36 = -13 wrong, no solution

for (-8, 2) :

3×-8 - 5×2 = -13

-24 - 10 = -13

-34 = -13 wrong, no solution

for (-6. -1) :

3×-6 - 5×-1 = -13

-18 + 5 = -13

-13 = -13 true, this is a solution

for (9, 8) :

3×9 - 5×8 = -13

27 - 40 = -13

-13 = -13 true, this is a solution
