Slope Formula: 
I am going to show you how to do this on problem 6, and you will do the rest of the problems.
Here are the steps to solving problem 6
Step 1) Substitute the coordinates into the slope formula
Step 2) Now Lets simplify the denominator, so we don't have two Subtractions symbols.
Step 3) Simplify
Step 4) We can still simplify more
Hope This Helps ... Good Luck
[The reason I didn't do all of them is because you need to know how to do them. Trust me later on knowing these is going to be very handy.]
