Question

Which statement about the ordered pairs (−9,3)and (2,−4)is true for the equation6x−y2=14?Both ordered pairs are solutions.(−9,3)is a solution to the equation.(2,−4)is a solution to the equation.Neither ordered pair is a solution.

Answer 1

Solution

We have the following points (-9,3) and (2,-4)

We have the following equation:

6x- y/2 = 14

we can rewrite this equation like this:

12x -y = 28

If we replace the first point(-9,3) we have:

y= 12*(-9) -28= -186

And for the second point:

y= 12*2 -28= -4

Then the correct answer is:

(2,−4) is a solution to the equation.
