Lesson details

Lesson outcome

I can recognise that the point of intersection of two linear graphs satisfies both relationships and hence represents the solution to both those equations.

Show transcript
More than one linear graph can be drawn on the same set of axes. A pair of coordinates which lay on the line satisfy the equation of the line. The pair of coordinates for the point of intersection satisfy both equations. Graphical software can be used to show this visually.
