E-Maths: General Equation and Graphs of Line


Line is part of us, in almost everything you see.

You must understand

  • what equation of line is,
  • how to find gradient,
  • how to find the x and y intercepts,
  • what's the relationship between a pair of parallel lines, (perpendicular lines are out of syllabus for E-Maths 4016)
  • how to write the equation of line given the diagram and lastly,
  • how to draw a line.

Do you love this topic on straight lines? Leave me your thoughts and reasons for your love/hate relationship toward lines.

  2. Dear Ai Ling,
    Hope you are well. I'm receiving mail from you since long time. I always read the topic touching you and I feel you are very good in Mathematics as Math is your passion. But you wrote "I enjoy coaching students who have challenges with understanding and scoring in 'O' Level A-Maths and E-Maths". My question is here, why only coaching? why not formal teaching? Actually, I don't have any idea about your Math Background.

    I'm Nasir Uddin. I did my MSc in Math from the university of Dhaka, Bangladesh in late 80's. I'm doing the job in ministry of education in Bangladesh as a teachers trainer.
    I have a nice similarity to you where Mathematics is my passion, I love Mathematics.

    Thank you very much.

    Thank you Nasir!
    Formal teaching has its constraints and it doesn't involve 100% teaching but other administrative matters in school too.
