Case 2: Linear Graphs

Linear graphs with coefficient 1 usually have a gradient, when the equation of the graph, y, is less than or more than 0. The exception is when y = 0, as the graph will be parallel to the x-axis. The gradient, when present, is always constant. There is no turning point or line of symmetry. Intersections with the x and y axis have a relationship with the gradient, where (y₁-y₂)/(x₁-x₂) = gradient.
