The answer is { (-3, 1), (0, 4), (2, 6) }. U use substitution to solve. So substitute x in Y = X+4

Substitute x with 2 so the equation now reads

Y = 2+4

=6

Remember the first number is always = x and the second number is always Y

Which of the following functions has the function rule y = x + 4?{ (0, 2), (-2, - 6), (1, 5) }{ (2, 6), (-3, - 7), (0, 4) }{ (-3, 1), (0, 4), (2, 6) }{ (-2, 2), (-1, - 5), (3, 7) }

{ (0, 2), (-2, - 6), (1, 5) }

{ (2, 6), (-3, - 7), (0, 4) }

{ (-3, 1), (0, 4), (2, 6) }

{ (-2, 2), (-1, - 5), (3, 7) }
