What are some questions that you can ask once you know the equation of a line. The equation of a line is y=mx+b. The b equals the y intercept  The m equals the slope. A question you might ask is "What is the slope?" I will answer you by saying "The slope is how much you go up by. For example the slope is rise over run. Say the rise is 1 and the run is 2. You would shoe that on a line graph. The line intercept is 2. You start at 2 and go up one and over to the right 2. 
Another question you might ask would be " Well, what if the number on top is negative. Then what would the slope be?"I will answer you by saying"If the number on top is negative then you would either go down 1 over to the right 2. Otherwise you would have to switch the negative to the bottom. Then you would go 1/-2. You would go up one and to the left 2."

Why are square roots called square roots? They are called that because a perfect square is perfect and 16 is a perfect square. Meaning that if you put 16 on all sides of a square the square would be cut in half it would be perfect triangles. The triangles would come out to be 4 on all sides. If you can put the # on a square and that square is a perfect and you can cut that square in half, and what you get is perfect triangles.
  What may be another name for square roots? Another name for square roots would be perfect square. That would be because they have two numbers that go are times by itself to become that number. Like a 144 is one because 12 times 12 is 144.

The Pythagorean theorem is a formula that you use for finding all sides of a right triangle. One situation you would use it would be when a girl is riding her bike out to her friends house she gets 5 feet away, and she remembers she had a gift for her friend she takes a short cut to her right and sees that it's in her bike basket. She goes back up and cuts through someones yard and gets back to where she was. 
 What you would do would be to
  1. First know your problem then know your equation.
  2. Next your equation is a^2+b^2=c^2
  3. Now all you have to do is solve.
