Each linear equation can be drawn as a line on a graph. The co-ordinate where the ... work out the y values for each equation. For example, put x = 0 into the equation y = 7 – 2x.

To find solutions from graphs, look for the point where the two graphs cross one another. This is the solution point. For example ... and \(y = x + 1\) using graphs. To solve this question ...
