Question

Which of the following is not a solution of the equation y=3x−4 ?

(2, 2)
(0, -4)
(4, 8)
(-1, -1)

Answer 1

(-1, -1) is not a solution to the system

Explanation:

Y = 3x - 4. Substitute the points for x and y

2 = 3(2) - 4

2 = 2 solution

y = 3x - 4

-4 = 3(0) - 4

-4 = -4 solution

y = 3x - 4

8 = 3(4) - 4

8 = 8 solution

y = 3x - 4

-1 = 3(-1) - 4

-1 = -7 not solution
