Question

Given: 1/3x + y = 15.

Which of the following are ordered pairs of this equation?

A){(-3, 14),(0, 15),(3, 16)}
B){(-3, 16),(0, 15),(3, 14)}
C){(16, -3),(15, 0),(14, 3)}

Answer 1

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

Answer 2

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
