We reviewed linear equations a little more today. You practised finding the equation of a line using the graph.

We remembered that for an equation in the form we have a slope of and a -intercept of . given two points on the line. Once we know the slope, we can substitute values in for and using a known point, then solve the equation for .

We practised on these graphs: Graphs of lines – find equations

For homework I asked you to complete the first two parts of this activity, as much as you are able. Come to see me before school or at lunch if you need help: Plotting Points and Finding Linear Equations
