Complete this sentence with the correct choice: y = 4 is a horizontal line with ________.

undefined slope.

a slope of 4.

a slope of 0.

None of the above will make a true statement.

Think this through...

If y=4, then x can be any number, but y will always be 4. Slope is defined as (the change in y)divided by (the change in x). If y doesn't change, that means your numerator will be 0.

Can you figure out the answer now?
