Which ordered pairs in the form (x, y) are solutions to the equation 7x – 5y = 28?
choose all answers that are correct.
a. (−6, −14)
b. (−1, −7)
c. (4, 10)
d. (7, 9)

we know that

If a ordered pair (x,y) is a solution of the equation, then the ordered pair must satisfy the equation

we have the equation

Let's verify all the cases to determine the solution to the problem.

case A) point

Substitute the values of x and y in the equation

-------> is  true

therefore

The point   is a solution of the equation

case B) point

Substitute the values of x and y in the equation

-------> is  true

therefore

The point   is  a solution of the equation

case C) point

Substitute the values of x and y in the equation

-------> is not true

therefore

The point is not a solution of the equation

case D) point

Substitute the values of x and y in the equation

-------> is not true

therefore

The point   is not a solution of the equation

therefore

the answer is

true !
