HELPPPPPPPPPPPPPPPPPPPP! ALGEBRA 1!

Answer 1

tHE ordered pairs in the sets shown below are of the form (x, y). In which set is y a function of x?

{(0, 3), (1, 4), (2, 4), (2, 8)}
{(1, 3), (2, 6), (3, 1), (6, 3)}
{(1, 3), (3, 1), (3, 4), (4, 3)}
{(1, -2), (1, 0), (1, 5), (1, 7)}

Answer 2

You can eliminate any sets where x is constant and y changes

e.g sets 1,3 and 4

The reason is that set 1 has the values (2,4) and (2,8), set 3 has (3,1) and (3,4) and finally set 4 has all values of x as 1 but the y value continues to change.

So the answer is set 2
