Lesson 10

10.1 Warm-up 10.2 Activity 10.3 Activity

Unit 7, Lesson 10

Relating Linear Equations and Their Graphs

Extra Support Materials for Algebra 1

10.1

Warm-up

Here are graphs of and .

<p>graph of a line with a positive slope and y intercept = 5.</p>

<p>exponential growth curve. y intercept = 5. </p>

What do you notice? What do you wonder?

10.2

Activity

Here are some equations and graphs. Match each graph to one or more equations that it could represent. Be prepared to explain how you know.
A has a negative slope and y intercept = 0. B is horizontal with positive y intercept. C has positive slope and y intercept = 0. D has positive slope and negative y intercept. E is a vertical line with negative x intercept. F has a negative slope and positive y intercept.
Choose either Graph D or F. Let represent hours after noon on a given day and represent the temperature in degrees Celsius in a freezer.
- In this situation, what does the -intercept mean, if anything?
- In this situation, what does the -intercept mean, if anything?

10.3

Activity

<p>graphs A, B, C, D, E, F. </p>

Without substituting any values for and or using technology, decide whether Graph A could represent each equation, and explain how you know.
Write a new equation that could be represented by:
1. Graph D
2. Graph F
On this graph, represents minutes since midnight and represents temperature in degrees Fahrenheit.
1. Explain what the intercepts tell us about the situation.
2. Write an equation that relates the two quantities.
