Title: Linear Graphs
Learning Objectives 
Level 6
To be able to demonstrate how to construct a table of values from a linear equation and use these to draw a linear graph.
How can these methods help us in the real world?
Level 7
To be able be explain the properties of a graph of the form y=mx+c without drawing the graph and use this information to quickly plot the graphs. 
What do the numbers in the equation y=mx+c tell us about the graph?



Resources 
We are now going to use equations to construct graphs (the first step is to construct a table of values).






Now you should have noticed a connection between the gradient, point the graph crosses the y-axis and the equation.




Homework
Two more questions from Ten Ticks - 6, 1, page 27
