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.

I like this blogpost. Yes, indeed straight lines are important to us. Since kindergarden we have been taught the importance of straight lines. Keep sharing Ai Ling! =)

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.

Nasir

Dhaka, Bangladesh.

Ai Ling says

Thank you Nasir!

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