In order to work with gradients and straight lines successfully, a good understanding of coordinates and linear graphs is needed ... Use these coordinates to find the gradient of the line.

The point slope form is particularly useful when you have these two pieces of information and need to find the equation of ... to quickly obtain solutions and graph the equations.

{2}x - 4\). First, find the perpendicular gradient and substitute this into the equation for all straight lines, \(y = mx + c\). If \(y = 3x - 1\) the gradient of the graph is 3. This means the ...
