# Linear Law,Just 1 Strategy Makes A Grade Difference

**What is Linear Law?**

It is a tool which will allow you to transform **non-straight line equation to straight line equation** so that you can plot a straight line. Most of the time, the axis will consist of* x* and/or *y *

One of the techniques involving **taking ****lg** (log base 10) on both sides of the given equation.

**Common Mistake! STOP**

This is one of the common mistakes I have highlighted in Top 7 Commonly Made Mistakes in Logarithm

**How To Counter This Mistake**

Very simple. Just **add in a bracket** on the **right hand side** of the equation.

Now, your y-axis will be lg y and x-axis will be lg x. Gradient = b and y-intercept = lg A
