You could include it in a Parent Teacher Conference folder. Both lines have the same rate of change. Time of weeks Coins Time weeks b. Answer will be any straight line that is below Hannah s line, goes through the origin, and has a positive slope. Padma also sees that she can buy Tootsie Rolls at the grocery store. How would this change affect the graph?

Use your rule to determine which stage has 58 blocks. Understanding the difference between discrete and continuous relationships is important but is not relevant to the learning at this point in the progression of linear relationships. The class member must make a table, graph, and equation for the story. Rise height total height Run depth total distance at Ratio you ve climbed on the ground level covered from ramp at this point stair-base beginning 12 inches in from the start of the ramp 24 inches in from the start of the ramp Where the ramp meets the top 4. Is it probable for the flower to continue to grow in this manner forever?

Prove that your pattern is linear using the representations geometric model, table, graph, and equation as evidence. Connect the Rule to the Pattern b Class Activity: Nate and Landon are competing in a 5 minute long Hot Dog eating contest. Representations of a Linear Pattern b Homework: Don s line is less steep meaning that his unit rate is smaller.

## 2.3j Class Activity: Use Dilations and Proportionality to Derive the Equation y = mx + b

Time of weeks Coins Time weeks b. As students examine many equations in slope-intercept form and interpret the slope and y-intercept they see the structure of the general form for a linear equation begin to emerge. Adequate time and practice is given for students to solidify their understanding of this crucial aspect of linear relationships. As the rate homewprk higher, the line gets steeper.

Hours x Cost y Equation: Students will expand their understanding of discrete functions when they study sequences in Secondary I.

# Identify proportional relationships (practice) | Khan Academy

Use the ordered pairs given in the table to test your chosen equation and explain your choice. They are the same line. I can discuss the similarities and differences between the two graphs including a discussion about proportionality and slope.

They further their investigation of slope and proportional relationships and derive the slope formula. Don did not add the right amount of bananas he doubled the amount of strawberries by adding 2 cups, but he also added 2 bananas.

This means that she will need 3 or 1.

For example, compare a distance-time graph to a distance-time equation to determine which of two moving objects has a greater speed. Which boy proportionl truck is moving the fastest? Use evidence from the context, graph, table, and equation to support homeworl answer. The cement comes out of the truck at a constant rate.

Measuring the Slope of Stairs and Ramps 1. The graph and table below describe a runner s distance from the finish line in the last seconds of the race.

This will bring up a negative rate relatinships change. Answers will vary 2. Partial Understanding 2 I can make some of the linear representations.

Stage 0 It is the number of blocks in step 0 the number of blocks the pattern starts with.

The cost to buy salt by the pound is less than sugar and flour. The next lesson will address why this is true.

The lesson lasted 3 hours. Stage 1 Stage 2 Stage 3 All representations show a rate of change of -3 and an initial value of Proportional Relationships b Class Activity: Will Doug finish the job in time? They will expand their knowledge of linear functions and constant rate of change as they investigate how other functions change in future grades.

It is okay if you do not use the formal term of Slope-Intercept Form. Representations of a Linear Context 1. Write at least two sentences that explain the similarities and differences between Agatha s and Fitz s relationship.
