The first class had a kids in it, the second had b kids in it, and the third class had c kids in it. kids from all three classes were equally divided between two buses. how many kids were on each bus?

i just took the test, the correct answer is .. 31.5 in.

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
