State whether the graph is linear or non-linear. Give a reason for your answer.

It looks like the graph or table of values related to these questions is missing from the image. I'll do my best to answer based on your partial work and common interpretations of such problems, but please note that for questions 1.1.7 and 1.1.8, I'll need the full pattern or graph to provide a complete answer.

Here are the answers based on the information available:

1.1.5 State whether the graph is linear or non-linear. Give a reason for our answer.
Based on your answer for 1.1.6, which describes a constant change, the graph is linear.
A graph is linear if the relationship between the variables shows a constant rate of change (a straight line). This means that
