MA5.3-8NA

Uses formulas to find midpoint, gradient and distance on the Cartesian plane, and applies standard forms of the equation of a straight line

Outcomes

Find the midpoint and gradient of a line segment (interval) on the Cartesian plane (ACMNA294)
- Use the concept of an average to establish the formula for the midpoint, M, of the interval joining two points (x1,y1) and (x2,y2) on the Cartesian plane: M(x,y) = (x1 + x2 / 2, y1 + y2 / 2)
