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

Thank you so much
