Linear Functions and Relationships

The video covers Math 8 Unit 5 Lesson 8, focusing on linear functions. It begins with a discussion on graph ordering, followed by an exploration of proportional relationships and graphing functions. The lesson then analyzes functions related to filling and draining tanks, compares savings rates using graphs and equations, and concludes with solving homework problems related to linear functions.

What is the main topic discussed in the introduction of the lesson?

• Polynomial functions

• Exponential functions

• Linear functions

• Quadratic functions

In Jada's lawn mowing example, what is the independent variable?

• The time spent mowing

• The number of lawns mowed

• The number of neighbors

• The amount of money earned

How is the conversion from feet to yards represented in a functional relationship?

• Multiply feet by 2

• Subtract 1 from feet

• Add 3 to feet

• Multiply feet by 1/3

Which tank starts with more water according to the given equations?

• Tank C

• Tank B

• Tank D

• Tank A

What indicates that a tank is draining in the given equations?

• A positive coefficient with time

• An increasing initial value

• A negative coefficient with time

• A constant value

Who started with more money in their account, Noah or Elena?

• Both started with the same amount

• Elena
