Rectangular coordinate system
Rectangular coordinate system - The position of a point in a plane is determined by two coordinates. The method is as follows: Two mutually perpendicular lines (straight lines) XX' and YY' are drawn as shown in the figure. These straight lines are termed as coordinate axes, the one (usually drawn h..

I love the interaction and ability to explain the process of math problem in depth! Would like see the same for all future lessons one on one! THANK YOU!!!
Even though I don't feel good, the tutor helped me by totally helping me understand!
Tutor are so organized and neat with their teachings. She set up everything that made the problems more understandable by showing them in such a simple manner, I feel I could really learn from them and pertain it to my class! :)
