Study Marco's height growth using the line graph and answer the questions.

Let’s go step by step using the line graph titled “Marco’s Height”.

The horizontal axis (bottom) shows Marco’s age from 6 to 18 years old.
The vertical axis (left side) shows his height in centimeters, from 20 cm up to 220 cm.

We’ll find each answer by locating the correct age on the bottom, going up to the purple dot on the line, and then reading across to see the height — or vice versa for questions asking about height first.
