Question

Given: 1/3x + y = 15.

Answer 1

The answer is B
you can substitute the(x,y)in the equation to find out the answer.
For example,Is (3,0) a point on 1/3x+y=15.
By Substitute x=3 and y=0 to the equation
1/3(3)+(0)=1,which is =/=15.
So you know that (3,0) is not a point on the equation

Answer 2

Given 1/3x + y = 15, the ordered pairs in the equation would be {(-3, 16),(0, 15),(3, 14)}, or choice B.
