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?

Using the pointslope equation, find the equation containing (2, 5) and slope m = 3
