Investigating Straight Lines: y=mx+c
Builds up from rules linking input to output (linear sequences) to writing the equation of a straight line. The emphasis is on the fact that the equation of a straight line expresses the relationship between the x and y coordinates of all the points on the line. This point is intended to be addressed before going into gradients and intercepts. Please tell me what you think.
