Expert Answer
Step 1: We draw two perpendicular lines OX and OY.
Step 2: On OX, we represent years, from 1997-2002 and on OY we represent the number of trees planted.
Step 3: On OY, we start with 400 and marks points at equal intervals of 200.
Step 4: The height of the bars are calculated according to the number of trees.
A kink (~) has been shown on the vertical axis showing that the marking on the vertical axis starts from zero but has been shown to start from 400 as the data needs.
