Show transcript
For straight-line sections of a graph, it is easy to calculate the gradient.
The gradient tells us the rate that one quantity changes with respect to the other.
The gradient gives the rate that the $$y$$ variable changes with respect to the $$x$$ variable.
The gradient can be interpreted in context and should be for real life contexts.
