IM 8.5.6 Practice: Even More Graphs of Functions
Match the graph to the following situations (you can use a graph multiple times). For each match, name possible independent and dependent variables and how you would label the axes.
Tyler pours the same amount of milk from a bottle every morning.
A plant grows the same amount every week.
The day started very warm but then it got colder.

Fill in the missing parts of the table.
The points with coordinates (4,8), (2,10), and (5,7) all lie on the line 2x + 2y = 24. Create a graph, plot the points, and sketch the line.
What is the slope of the line you graphed?
What does this slope tell you about the relationship between lengths and widths of rectangles with perimeter 24?
