Linear Law O Level A Math Question

Linear law O Level A math is predictable. The structure of the questions from this topic on Linear law is very standard. You first draw a straight line graph (given some data). Next with the straight line graph, you will find the vertical axis and the gradient so as to find the unknown constants. Once you have found this, the last part of the question often involves finding the value of a variable, given the value of another variable.

In this video, we go through a typical linear law (or straight line graph) step-by-step. Check out more about typical Linear Law questions tested in O Level A Math in this post here:
