2.1A HOMEWORK PROPORTIONAL RELATIONSHIPS

Develop a procedure for calculating the slope without graphing each point. Students often confuse the given information with rate of change and fail to recognize what quantity each number in the ordered pair represents. Which bakery offers the better deal? How many new blocks are added to the pattern from one stage to the next? Use the information given above to determine how much it will cost to buy 10 cupcakes at the bakery with the better deal.

Calculate it in two different ways. Toby will cross the sidewalk before the cyclists reach him. After a few different rules are on display, ask students how we can have different rules for the same pattern. The unit rate for Besty s smoothie is 1. Use evidence from the context, graph, table, and equation to support your answer. Concepts and Skills to Master:

Construct viable arguments and critique the reasoning of others. Story B 0, 4 4, 0 Rate of change: If using a bottle, the water level in the bottle should be parallel to the side of the bottle. This means that the object is enlarged or reduced in size.

Label the sketch base and height, for example: Relatiknships on they are asked to make their own graphs and must use the correct units and labels to communicate their thinking. ho,ework

2.1a homework proportional relationships

What is the total distance total depth for all steps you will need at the base for all of the stairs? It is sufficient at this point for a student to have a conceptual understanding of the structure of a linear relationship.

Identify proportional relationships (practice) | Khan Academy

Comparing Proportional Relationships Proportional relationships can help us to compare and analyze quantities and to make useful decisions. Where do you see the y-intercept in the table and in the equation? No, the flower will eventually die or stop growing; otherwise it would get too big to support its weight. Create propoortional table for this graph, Time Distance 3,23 0,5 Highlight on the graph where you can see the rate of change. Students are technically finding slope but in a very informal way.

What is the y-intercept of the graph? The patterns in the problems below exhibit linear relationships. Complete the table below to show the relationship of white to pink flowers in each vase. The cement comes 22.1a of the truck at a constant rate.

Graph this relationship on the same coordinate plane as Agatha s line on the propodtional page. Often the rate at which a relationship changes is shown by seeing that the changes from one measurement to another are proportional; that is, the quotient of the change in y values with respect to the x values is constant.

2.1a homework proportional relationships

This is the proportional constant for this relationship. Write an equation that represents the number of hotdogs h for each boy after t minutes.

Fill in the missing items in the table if x represents the number of weeks that have past and y represents the propottional of the flower. Nate has a special strategy to eat 4 hot dogs before the competition even begins to stretch out his stomach.

What do you notice about the ratio y for Grace? Don and Betsy are making super smoothies to re-energize them after a long workout.

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

Write everything you can say about the mouse and the distance she is from the cheese during this time. Students begin this chapter by reviewing proportional relationships from 6th and 7th grade, recognizing, representing, and comparing proportional relationships.

Context dollars per week; Graph is a line; Table constant difference of in the difference column; Equation: He gets paid the same rate every hour. Change the percent to a decimal and then change the decimal to a fraction 8WB Is it probable for the flower to continue to grow in this manner forever?

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

Currently, she does not have any money saved. Complete the table that shows the amount of money Agatha makes for selling up to three bags of popcorn.

In addition to writing equations you can represent real-life relationships in others ways. Students are not actually building the prooprtional and ramps but designing them.
