Which statement about the ordered pairs (3, −8)(3, −8) and (4, 4)(4, 4) is true for the equation 3x−y4=11
sleet_krkn [62]
The answer is D.) Neither ordered pair is a solution.

The reason being:

If we look at the ordered pair (3,-8) and plug it into the equation like so:

3(3)-(-8)4=11
9-32=11
-23=11
FALSE

Now let's look at the ordered pair (4,4):

3(4)-4(4)=11
12-16=11
-4=11
FALSE

We see that neither ordered pair works, so the answer is D.) neither is a solution.

Hope this helped :)
