The ability of mathematical modelling is a process of thinking and a process in describing a relationship between mathematics and real-world problems. It is considered to be more easily understood by pouring in the form of models or images. Mathematical modelling acts as a bridge connecting real problems with formal mathematics, it is important because it simplifies and clarifies in understanding the concept of mathematics. One of the algebraic concepts taken in this research is the concept of line equation, where to understand the concept required a mathematical modelling process. The objective of this research is to describe the mathematical modelling ability of eight grade students for the line equation. The research methodology used is qualitative descriptive, with the subject of research is eight grade students of Junior High School. The instrument of the research is questions of mathematical modelling and interviews with students. The conclusions of this study indicate that junior high school students in general still have difficulty in doing mathematical modelling, especially on the line equation. Based on the results of this study, the writer made as a preliminary study for further research on Dissertation to select appropriate models and teaching materials to improve students' mathematical modelling. © Published under licence by IOP Publishing Ltd.
