LET’S TRY ONE
Find the slope through (1, 2) and (4, 8).
2
(8 − 2) ÷ (4 − 1) = 6 ÷ 3 = 2.
Learning steps & teaching tips
Divide vertical change by horizontal change using consistent point order.
- Subtract y coordinates in the same order as x coordinates.
- Work through the example. Explain how its evidence supports the answer.
- Try a new question; use the explanation to check your thinking.
Try it together
Write or draw your own example with different numbers. Solve it, then ask a partner to check the method as well as the answer.
