Part 1: Interpreting Word Problems

The equation below can be used to determine how much it costs (y )to rent ice skates for (x) hours

What is k (Constant)?

What does k represent in this situation?

Using the equation

1. If you rented the skates for 4 hours, how much do you have to pay?

2. If you had to pay $42, how many hours did you rent the skates?

#2

The equation below can be used to determine how many boys, y, are in sixth-grade class that has x girls.

Y=5/6x

If there are 12 girls in the class, how many boys are in the class?

Part 2: WritingEquations for y=kx

Finding k in a word problem

You want to find the RATE

What is Rate (k)? y/k

1. Makena charges $28 dollars for 3 hours of swimming lessons.

2. Sara charges $18 dollars for 2 hours of swimming lessons.

• The table shows the amount of money Nasir makes for different

amounts of time he works.

• Determine whether there is a direct variation between the two

sets of data.

• If so, find the equation of direct variation.

• Graph the variation (Make sure to label each axis)

direct variation; y = 12x

Real Life Application

Jasmine earns $12.00 for every 2 hours she babysits. Last week, she worked for 15 hours. How much money did she earn?Steps: 1. Find the rate (k)2. Write an equation3. Substitute 15 into your equation

The cost of a plane ticket varies directly with the amount of people. The cost for 2 people costs $500. What is the constant of variation? Write an equation that represents

this situation

Leigh Parker earns $10 for every 5 chores she does. If x represents the number of chores she does, write an

equation that will tell how many dollars (y) she will earn.

How much do things really cost?!?!?

Direct variation Project You have to work for the item that you PICKED!!!! Use the NGMS Times, you must pick ONE job that you want to doFollow the project step by step. Afterwards, you must present your project in the most creative way possible, by only using the construction paper and graph paper provided The rubric of how I’m grading it is at each table Don’t worry….there will be helpful breaks along the way!
