TRUE OR FALSE

1.The set of ordered pairs {-1, -1), (-2, 20), (0, 3), (5,3) } defines a function.

this is true.
there is only one value of y for each and every value of x in the set.


2.The set of ordered pairs {(x, y) | y – 2x = 4} defines a function.

y - 2x = 4.
solve for y and you get y = 2x + 4
this is a straight line.
a straight line is a function because there is only one value of y for each and every value of x.
this is true.
