Preview Challenge Tomorrow is Joshua and Benjamin’s birthday. Joshua is 5 years older than Benjamin. How can we represent Joshua’s age with an equation. Would this represent a proportional relationship? Justify your answer. What are your initial conjectures? Date (8.5B) I will represent linear Lesson Objective Non-proportional situations with equations in the form of y = mx+b Given 4 problems, I will represent linear Demonstration of Non-proportional situations with equations Learning in the form of y = mx+b with 100% accuracy. Essential Question How can we use equations to represent linear non-proportional situations? Academic Vocabulary Vocabulary Review Words ● linear equation ● slope-intercept form of an equation ● y-intercept ● rate of change ● variables I Do The length of a rectangle is 5 inches more than one-fourth the width, w. Which equation represents this relationship? A. B. C. D. l=2w+5 l=¼ w+ 5 l =¼ w-5 l=2w-5 Width (w) l=¼ w +5 Length (l) 4 ¼ (4) +5 6 8 ¼ (8) +5 7 12 ¼ (12) +5 8 Justify your answer. We Do Melinda has $6 more than three times as much money as her brother, Lester. Which equation represents the relationship between Melinda’s money, m, and Lester’s money, L? A m = 8L+2 B m = 2L+8 C m = 2L-8 D L =2m+8 I Do The cash register subtracts $2.00 from a $50 gift card for every large drink the customer buys. Which equation represents this situation? A y = 50x-2 B y = 2x-50 C y = -2x+50 D y = -2x-50 Could the equation y= 50-2x represent this situation ? Explain. How do you know that this relationship is nonproportional? We Do The cost (y) of renting a jet ski at a lake is $20 per hour(x) plus $12 for lifejackets. which can be used to calculate the total amount you would pay for renting the jet ski. A B C D y = 12x+20 y = 20x-12 y = 12x-20 y = 20x+12 Y’all Do Tomorrow is Joshua and Benjamin’s birthday. Joshua is 5 years older than Benjamin. How can we represent Joshua’s age with an equation. Would this represent a proportional relationship? Justify your answer. Write an equation to represent the relationship between Joshua and Benjamin’s age. Y’all Do (continued) Create a table of values for Joshua and Benjamin’s age. Could the relation between Joshua and Benjamin be proportional? Is it possible?
