##### Stage: 3 Challenge Level:

Explore the relationship between simple linear functions and their graphs.

### Surprising Transformations

##### Stage: 4 Challenge Level:

I took the graph y=4x+7 and performed four transformations. Can you find the order in which I could have carried out the transformations?

### Translating Lines

##### Stage: 3 Challenge Level:

Investigate what happens to the equation of different lines when you translate them. Try to predict what will happen. Explain your findings.

### Reflecting Lines

##### Stage: 3 Challenge Level:

Investigate what happens to the equations of different lines when you reflect them in one of the axes. Try to predict what will happen. Explain your findings.

### Diamond Collector

##### Stage: 3 Challenge Level:

Collect as many diamonds as you can by drawing three straight lines.
