Pi is a never-ending decimal, but we sum it up to 3.14. On Thursday is Pi day, but it's also my mom's birthday. People celebrate with having pie. 
     Pi tells us things about circles, such as radius. You would multiply the number given by 3.14 to get your circumference of the circle. I still can't grasp the idea of how it works, but it does work. Pi is a very special number. Without it, how would we solve problems involving circles? Pi can be very helpful; In fact, we couldn't solve circle problems without it! Pi tells us the circumference of a circle (circumference is the distance around the outside of the circle). 
     

     Finding the equation for a line is not always easy. That was the part I struggled with, but the slope was just fine. 
     To find the equation of a line, you start at a point. Remember, rise over run. I remember which is which by: rise is going up and when we run, we run across the grass. Then you add the distance from the y-axis. This will now be your equation. 
     The Rise over run will be represented as a fraction. for example, if the rise is 5 and the run is 8, it will look like this: 5/8. Then, lets say that the _distance from the y-axis is 5. The finished equation will look like this: y=5/8+5. It's not very difficult when  you get the hang of it, but I obviously haven't.
