Given one point and the gradient
* Substitute the gradient for m in y=mx + c
* Substitute the x-values and y-values given into the equation
* Solve the equation to find c
* Write out the equation
Given two points
* Draw a sketch showing the two points
* Work out the gradient of the line using a triangle
* Use method 1 and one of the points given to find the equation
Positive or negative
If the line slops down then the gradient is negative
