Question

Which of the ordered pairs in the form (x, y) is a solution of this equation?
6x-y/2=14
(-9, 3) (2, -4)

A.
Neither is a solution.

B.
The first is a solution, but the second is not.

C.
Both are solutions.

D.
The first is not a solution, but the second is.

Answer 1

try plugging the points in the equation and whichever point satisfies the equation that will be the right answer

Answer 2

just substitute each pair and see if they are true

(-9, 3) so x = -9 and y = 3

\[6 \times (-9) - \frac{3}{2} = -54 - \frac{3}{2} = ?\]

will this equal 14...?

next point (2, -4) x = 2 and y = -4

\[6 \times 2 - \frac{(-4)}{2} = 12 + \frac{4}{2} = ?\]

which ordered pair has 14 as an answer

Answer 3

the first one?
