Question

Which is a solution to the equation y = 3x + 1? A.
(3, 10)


B.
(2, 6)


C.
(1, 5)


D.
(0, 3)

Answer 1

Just plug in a x value from each of your answer and see if the right y value comes out

Answer 2

You just have the plug in the coordinates into the equation. (x,y) so for :
A. (x,y) = (3,10) - > y = 3x + 1 -> 10 = 3(3) + 1 -> 10 = 10 yes.
B. (x,y) = (2,6) - > y = 3x + 1 -> 6 = 3(2) + 1 -> 6 = 7 no.
C. (x,y) = (1,5) - > y = 3x +1 -> 5 = 3(1) + 1 -> 5 = 4 no.
D. (x,y) = (0,3) -> y = 3x + 1 -> 0 = 3(3) + 1 -> 0 = 4 no.

Ok, Thank you very much!
