Which ordered pair is a solution of y=7x-3

Try each ordered pair in the equation.

y = 7x - 3

Try (1, 4)

1 is x and 4 is y

y = 7x - 3

4 = 7 (1) - 3

4 = 7 - 3

4 = 4 This is a true statement, so ordered pair (1, 4) is a solution.

Try (-1, - 4)

y = 7x - 3

-4 = 7 (-1) - 3

-4 = - 7 - 3

-4 = - 10 This is a false statement, so the ordered pair (-1, - 4) is not a solution.

Answer: (1, 4) is a solution.
