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.
