Recognizing patterns:
1) Look at the pattern, how is it growing? Thinking about the pattern is=n different ways can help you recognize how it is building
2) Are there any constants in the pattern? Are there parts of the pattern that repeats in all figures?
3) Make a table of values. (Input/output table) Look for patterns in the table
4) What expression describes the pattern? Does this expression work for all figures in the pattern?

Desmos Activity: Match My Line (link in powerpoint)
•When given an equation to graph:
•make a table of values using any values of x (preferably a positive, a negative, and zero).
* hint - use multiples of the coefficient of y when making the table of values.
•Substitute the numbers for x into the equation
•solve for y.
•Then plot the points on the graph.
Topic 5 - Interpolation & Extrapolation
Interpolation: Estimating values that lie between two data points on a graph
Extrapolation: When a relationship is linear, we assume that the relationship continues. Use a ruler to extend the line of a graph to predict the values of two data points.
