Graphing age and height

Math 9 Algebra 1 homework for 8-24
Find 7 to 10 people.  For each person, write down their age in years and months, and their height in inches.  Make a graph with age along the x-axis and height along the y-axis.  Plot the age and height information as dots showing ordered pairs of numbers
Hints:
“Plot a point” means use age for x and height for y.
If you are fourteen years old and your birthday was in May, it has been 3 months since your birthday (June, July, August) so you are 14 years and 3 months old.
If you are 5 feet 3 inches tall, 5 times 12 inches per foot = 60 inches, and add the other 3 inches, so you are 53 inches tall.
