Lesson 17: Lesson 17: Two related quantities, part 2

# Ratios on coordinate plane

Ratios represent the relationship between two quantities and can be visualized on a graph. When the ratio is constant, the points form a straight line, illustrating the connection between the quantities. Examples include bakers using flour, car wash charges, and earnings from shoveling snow.

• Don't worry, you will understand, it will just take some time and thinking through.

Let's look carefully at an example. Suppose a group of kids is invited to a party. Every kid is supposed to get two cookies each at the party. If four kids get invited, how many cookies would you have to make so that there are just enough cookies to give each child his or her two cookies? If you reply with the answer we can keep working through this.
