Interpreting Linear Relationships Through Graphs

This video tutorial explains how to interpret the direction of linear relationships by analyzing graphs. It covers the basics of linear relationships, including initial value and rate of change, and how these are represented on graphs. The tutorial discusses positive and negative slopes, using examples like ice cream and hot chocolate sales to illustrate how input and output move in relation to each other. It also explains how to identify zero slopes and provides practical examples to reinforce understanding.

What are the two key components that define a linear relationship?

Explain the concept of slope in the context of linear relationships.

Describe what happens to ice cream sales as the temperature increases.

What does a horizontal line on a graph indicate about the relationship between input and output?

How does the direction of a slope change when the input and output move in opposite directions?

Can you provide an example of a positive linear relationship and explain its characteristics?

In a negative linear relationship, what happens to the output as the input increases?
