Graphical Simultaneous Equations : Theory

• • To solve simultaneous equations graphically, all we need to do is draw the graphs for the 2 equations given, and find the point where they cross 
  • Then write down the value for x and the value for y
• • You can use a linear equation to find the estimates to the solutions of a quadratic equation, by drawing  a linear graph over the quadratic graph 
  • Then, find the 2 points where the linear graph crosses the quadratic graph 
  • You can use an xy table to draw the linear graph
