Question 663734: Given: x + 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 by ReadingBoosters(3246)   (Show Source):
You can put this solution on YOUR website! Starting with x+y=15
Convert to linear equation format y=mx+b
y = -x + 15
...
Use -3, 0 and 3 for x and solve for y
y = -(-3)+15 = 18: (-3,18)
y = -(0)+ 15 = 15: (0,15)
y = -(3) +15 = 12: (3,12)
A & B are false
y = -(16)+15 = -1: (16, -1)
y = -(15)+15 = 0: (15,0)
y = -(14)+15 = 1: (14,0)
C is false also
...
D none of the above
