U1A2- Investigation

Print this page only to have the grids to create the scatter plots.

Once you have completed the scatter plot, either take a picture or scan the graph and paste it into the document.

1. Side Length and Perimeter -remember to label the axes

2. Side Length and Area - remember to label the axes

Investigations with Squares - 1. Side Length and Perimeter

Use this page to record your data, add the scatter plot and analyse your results.

Collect and Represent the Data

• o Use the squares to investigate
• o Record your data into a table of values.

Side Length	Perimeter

• Paste your scatter plot below (from above).

Using the online graphing tool:

• If you think a straight-line best fits the data, then selectLinear Relation:https://www.desmos.com/calculator/thhqsxziln
• If you think a curve best fits the data (i.e. non-linear relation) then selectQuadratic Relation:https://www.desmos.com/calculator/lb8m0l1fw3.
• What does the x variable represent in this relation? __________________
• What does the y variable represent in this relation? __________________

• Record the algebraic representation ( i.e. the equation) from the graphing tool. Rewrite the algebraic representation to reflect the variables for this relation.
