Plotting straight line graphs
To plot a graph from its equation
- Re-arrange equations into form y = mx + c
- Pick 3 sensible points for x, including 0, then solve for y.
- Plot points on grid.
- Join with a straight line that goes through the y
- Graph will cut the y axis at (0,c) and have gradient m.
Plot the graph y - 2x = 4
