Review Lesson 4-2:
Graph the functions on the same plane at desmos.com.
Zoom and pan your graph to establish an appropriate viewing window.
Take a screenshot of your graph.
Upload or paste your screenshot to the canvas.
Review Lesson 3-2: Solve the system by elimination on the canvas. Show each step and write the solution in the space provided.
You may also complete your work on paper or on a whiteboard and upload a clear picture of it to the canvas.
Review Lesson 2-2: y varies directly with x. Match each direct variation with its solution.
If y = -2 when x = 4, find y when x = 7.
If y = 2 when x = 5, find y when x = 2.

0.8
-3.5
Review Lesson 1-3: Match each expression with its simpler form.
x² + 2x - 1
x² + 5x - 1
Vocabulary Review: Identify the graphs that are NOT parabolas.
Use Your Vocabulary: Match each description on the left with the equation that models it on the right.
The string section of the orchestra has twice as many violins as cellos.
There were 100 shin guards in the closet, and each player took 2.
There are two eggs per person with one extra for good measure.
y = 2x + 1
y = 2x
y = 100 - 2x
Modeling: Consider the table showing a meteorologist's predicted temperatures for the day.
Which calculator screen below shows the correct data entry for a quadratic model?
