Using logarithms, we can express \(y = k{x^n}\) in the form of the equation of a straight line \(y = mx + c\). Shown below is a straight line graph when \({\log _{10}}y\) is plotted against ...
The graphs above, \(y = 2x + 1\) and \(y = 2x - 2\) have the same gradient of 2. The lines are parallel. State the equation of a line that is parallel to \(y = 3x + 7\). To be parallel ...
