Question

Which of the following is a solution to the linear function:

2x + 4y = 16
(2, 4)
(4, 2)
(-2, – 4)
(4,0)

Answer 1

B. (4, 2) is most likely the answer

Answer 2

(4,2) is the answer because if you substitute the x- coordinate and the y- coordinate with their values you get 2(4) + 4(2)= 16. This equation could be simplified to 8+8=16 which is true and linear.
