Question

Which ordered pair is a solution of the equation y = 3x?
A.(–2, –9)
B.(–8, –18)
C.(–8, –3)
D.(–10, –30)

Answer 1

D.(–10, –30)

Answer 2

-30 = 3(-10)
-30 = -30

Answer 3

.(–10, –30)

substituting in the eqation y = 3x we get,

\[ -30 = 3(-10) \Rightarrow -30 = -30 \]

Hence,satisfies.

Answer 4

Since the relationship between x and y is simply "Y is three times X", you need to find the Y value that is thrice the X value. Since -10 times 3 = -30, the answer is D.
