Which ordered pair is a solution of the equation y=4x

Choices

(1,3)

(-1,-4)

(-4,-1)

(1,-4)

(-1,-4)

Step-by-step explanation:

We shall substitute them in and see

y = 4x

(1,3)

y = 4 (1) = 4 That is not 3 Not a solution

(-1,-4)

y = 4 (-1) = - 4 This is a solution

(-4,-1)

y = 4 (-4) = - 16 This is not - 1 Not a solution

(1,-4)

y = 4 (1) = 4 This is not - 4 Not a solution

your answer is (-4,-1)
