Test Item Specifications
- a table of values;
- the - and -intercepts;
- two points;
- the slope and a point; or
- the equation of the line in slope-intercept form, standard form, or point-slope form.
- In Lesson 1 students use mathematical models (tables and equations) to represent the relationship between the number of revolutions made by a "driver" and a "follower" (two connected gears in a system), and they will explain the significance of the radii of the gears in regard to this relationship.
- In Lesson 2 students mathematically model the growth of populations and use exponential functions to represent that growth.

Sample Test Items (1)
| Test Item # | Question | Difficulty | Type |
| Sample Item 1 | Roger went to a garage sale where hardback books sold for $5 each and paperback books sold for $2.50 each. He has $20 to spend. The equation below can be used to find how many books of each type Roger can buy, where x is the number of hardback books and y is the number of paperback books. 5x + 2.5y = 20 Which of the following shows the graph of this equation? |
