The equation y = x + 3 represents a linear function. Which ordered
pair does not lie on the graph of this function?
A) (-10, -7)
B) (13, 16)
C) (-14, -11)
D) (-20, 17)

Answer 1

D) (-20, 17)

Explanation:

y = x + 3 (substitute the numbers & check if the equation is still true)

-7 = -10 + 3 -> -7 = -7

16 = 13+3 -> 16 = 16

-11 = -14 + 3 -> -11 = -11

17 = -20 + 3 -> 17 = -17 (not true)
