Concept

Objective: Students will calculate and interpret slope from tabular data.

Estimated Time: 12 minutes

Standards:
HSF-LE.A.1HSF-IF.B.6

Rate of change is Δy/Δx. In linear tables, this value is constant and equals slope.

Try it

From points (1, 5) and (4, 11) in a table, compute the rate of change.

Concept Check

If Δy = 12 and Δx = 3, slope is:

Concept Check

A constant positive slope means the function is:

Common Misconception
Always verify your result in context instead of trusting a first pass.

Compute slope from a table

These steps are out of order — can you fix them?

1.Choose two data points
2.Find Δy
3.Find Δx
4.Compute Δy/Δx and interpret
