Linear Relationship: A correspondence between two variables that form a line when graphed. Examples Distance and Time = speed Paycheck and Time = pay rate
Annette started her own business raking lawns in her neighborhood. With bags and tools, she charges $8.75 per lawn. • Write a routine to find the earnings after raking any number of lawns. • Create a table of the earnings from the first 10 lawns. • Graph the table.(X-axis = lawns,y-axis= $) • Estimate number of lawns needed to save $99.95 for a new graphing calculator.

3.2 Investigation: “On the Road Again” • Read investigation steps 1-5 on page 167. • In your notes: Write a recursive routine for each vehicle. (Rate of travel) • Write a DIRECT equation for each car. • Complete table and graph. (Use a different color for each vehicle on the graph.) • List and answer your group’s assigned question in your notes. Reporters: Prepare to share your group’s response.
Warm-up Leo lives 4.2 miles from his friend’s house. It is 4:35pm and he needs to get home by 5:00pm. He bikes constantly at 9 mph. Question: Will Leo make it home on time? Write a recursive routine. Create a table and graph the data. Is Leo early or late? By how much? How fast must he travel to get home by 4:50?
Warm-up Solutions Answer: Leo will be home on time, with 2 minutes to spare. Also, Leo must travel at 12.6 mph to be home by 4:50 pm.
