Lesson 4: Ratio application

# 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.

## Want to join the conversation?

• Does the x cordinate always come first
• Yes, X is always first... think about it as the alphabet x comes before y on the alphabet
• when do you use ratios and coordinates?
• Say you are landscaping, and you are planing to have 5, 1 foot by 1 foot flower beds placed throughout the 10 by 20 lawn. You need to be able to tell the ratio of dirt for the flower beds, to the amount of grass.
• When do use this in real life?
• If you got stranded on an island, and all you had was a map, and a corded phone, you would need to call out your latitude and longitude, which is close enough to a grid.
• Glad to see people from 2023
• Glad to see people from an hour ago
• Which kind of ratio should you use? Either 3;5 Say, or 3/5?

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.
