Graphing: Make a scatter plot of the data. Consider the correlation between variables. Zoom and pan your scatter plot to establish an appropriate viewing window.
🔍 Pro Tip: You may need to zoom in or out as you plot the points to keep the labels out of your way.
{(0,6),(1,4),(2,4),(4,1),(5,0)}
Click a Graph tab (Graph 1, Graph 2, and so on) for each graph you need to plot.
Click on the graph background to add a point. Drag a point or type in x and y coordinates to edit its position. Click on a point to delete it.

Review Lesson 2-2: Tag each equation based on whether y varies directly with x. If it does, also tag it with its constant of variation.
y varies directly with x
y does NOT vary directly with x
constant of variation: -5
constant of variation: 3
constant of variation: 100
y = x + 3
y = 100x
-5 = y + x
5x + y = 0
Describe the correlation between the variables in the previous item.
Negative correlation
No correlation
Positive correlation
Vocabulary Review: Identify each statement based on whether or not it is an inequality.
15 < 32
46 > 45
17x = 34
-27 ≠ 3x
Inequality
NOT an inequality
Vocabulary Review: Complete each inequality with an inequality symbol from the left.
<

-2 __?__ 1
0.05 __?__ 0.5
8/6 __?__ 16/6
|-3.5| __?__ -4
Use Your Vocabulary: Categorize each inequality based on the boundary line of its graph.
