Question

Which ordered pair is a solution to the equation y = -6x?

(12, -2)
(3,-9)
-10.60)
(18, -3)

Answer 1

(-10; 60)

Explanation:

y = -6x

(12; -2)

-2 = -6 · 12

-2 = -72 - no

(3; -9)

-9 = -6 · 3

-9 = -18 - no

(-10; 60)

60 = -6 · (-10)

60 = 60 - yes

(18; -3)

-3 = -6 · 18

-3 = -78 - no
