Pasangan bilangan ( , ) dinamakan titik (point) dalam 2, misal suatu titik P dapat ditulis ( , ). Bilangan x dan y disebut koordinat dari titik P. Untuk menggambarkan titik-titik di 2 secara geometris, koordinat x dan y dianggap berada pada dua garis bilangan yang berbeda yang membentuk suatu sistem koordinat. Garis bilangan tersebut dinamakan sumbu koordinat. Sumbu koordinat tersebut digambarkan saling tegak lurus dan membentuk suatu sistem yang disebut sistem koordinat siku-siku. Pada 2 sistem ini dinamakan sistem koordinat-xy atau sistem koordinat kartesius (Cartesian system) yang dibangun oleh : Sumbu x (x-axis) yaitu garis tempat semua titik yang mempunyai koordinat (x, 0).

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
