I have been looking at Linear Graphs with year 10 and we started looking at problems that I might plot on a graph. We also looked at the connection and patterns between groups of co-ordinates.

We looked at this problem early on and discussed how we knew which lines were equal in length

We then looked at a grouped of lines we had plotted and looked at the connection between the line and equation that matched it. We noticed all the lines were parallel and increased by the same “step” each time.

We also looked at what happened if the y-intercept was the same but the gradient different.

We looked at some DESMOS activities and then we looked at different problems related to parallel lines

## One thought on “Gradient”
