Unit Rate in Proportional Graphs Assessment

The video tutorial introduces a new notes packet covering units three and four, focusing on proportional relationships. It explains how to graph these relationships and interpret the unit rate as the slope of the line. Key vocabulary such as 'slope' and 'unit rate' is discussed, along with the equation y=kx for proportional relationships. The tutorial also covers how to interpret graphs, identify 'pretty points,' and calculate the unit rate from given data.

What should you do if you do not have the new notes packet?

• Ask the sub for a packet

• Continue watching the video

• Use an old packet

• Skip the lesson
