Activity 1

A walk on the grid

Method

On the graph, a man is standing at the point A(1, 2).
From A he walks straight to the right and reaches a point B.
From B he walks straight up and reaches the point A'(7, 6).
Look at his path on the graph and discuss the questions below.

Discussion

How many units to the right and how many units up did he walk from A(1, 2) to reach A'(7, 6)?
How can the pair of numbers for the move to the right and the move up be written?
How can the relation between the point A(1, 2), the pair of numbers and the point A'(7, 6) be shown?
