Basic straight line coordinate geometry

Simon Clay
This worksheet illustrates features of straight lines including equation and gradient of a straight line as well as mid-point and length of a line segment.
By hiding various features and moving the points A and B you can generate questions based around this subject knowledge and easily test your answers by revealing the hidden features. Example: - Hide everything apart from points A and B. Move points A and B to a chosen location. What is the mid-point of AB? How long is AB? - Display only the gradient and the mid-point. Give an example of the possible coordinates of A and B. - Display only B and M. What are the coordinates of A?
