E-Math -Coordinate Geometry - Equation of a Line

Topic: Coordinate Geometry

Some students assume that the number beside x is always the gradient.

In the example above, they assume that the gradient is 3, where in 

actual fact the gradient is 3/7. You need to change the linear equation

into the form of y= mx+c to find the gradient (m).

When lines are parallel they have the same gradient. So you can
"borrow" the gradient of a line to find the equation of the other 
line.

I created this Blog after my students told me that there is very little information about how to solve GCE O Level Math and Additional Math (A-Math) questions on the internet. Even if they manage to find, the solution were for very basic questions. I am a Full-time Math Tutor in Singapore. I tutor mainly in Northern Singapore (Woodlands, Chua Chu Kang, Bukit Panjang, Yishun and Sembawang). I also tutor in Johor Bahru.
