Please Help Much needed

Answer 1

I think you meant:
What ordered pair in the form (x,y) is a solution of ....

1.
3x-4y=21
You will just have to test each of the given choices in the equation.
I will do (-2,-3) , you do the others
LS = 3(-2) + 4(-3)
= -6 - 12
= -18
≠ RS
So (-2,-3) is NOT a solution

Keep going until you find the one where LS = RS
(Left Side = Right Side)


Can't tell for the others,since you gave no choices, unless those given apply to all.
In that case, just keep chugging along with my method
