Question

Which ordered pair is a solution of the equation y=7x-2?

1) (3,15)
2) (-1,-10)
3) both (3,15) and (-1,-10)
4) neither

Answer 1

The correct ordered pair is neither (3,15) nor (-1,-10). Hence, option 4) is correct.

Step-by-step explanation:

The equation is y = 7x - 2. To determine which ordered pair is a solution, substitute the x-coordinate and y-coordinate of each option into the equation.

Option 1: (3,15)

15 = 7(3) - 2,

15 = 21 - 2,

15 = 19,

Option 1 is not a solution.

Option 2: (-1,-10)

-10 = 7(-1) - 2,

-10 = -7 - 2,

-10 = -9,

Option 2 is not a solution.

Therefore, the correct answer is Option 4) neither.
