Question

Which of the following is a a solution to the equation y=3x-1
a) (4,1)
b) (2,5)
c) (4,3)
d) (0, -3)

Answer 1

For option a, y = 3(4) - 1 = 12 - 1 = 11                  [not correct]
For option b, y = 3(2) - 1 = 6 - 1 = 5                      [correct]

Therefore option b is a solution to the given equation.
