Question 1(Multiple Choice Worth 1 points)
(02.04 LC)
What is the equation of a line that contains the points (2, β2) and (0, β2)?
y = 0
x = β2
y = β2
x = 0
Question 2(Multiple Choice Worth 1 points)
(02.04 MC)
Choose the equation that represents a line that passes through points (β3, 2) and (2, 1).
5x + y = β13
5x β y = 17
x β 5y = β13
x + 5y = 7

Henry has $21.50 to ride the trolley around San Francisco this week. It will cost him $0.50 every time he rides. Identify the dependent variable and independent variable in this scenario.
The number of rides and the total cost are both independent variables.
The number of rides and the total cost are both dependent variables.
The total cost is the independent variable, and the number of rides is the dependent variable.
The number of rides is the independent variable, and the total cost is the dependent variable.

Write the equation of a line that goes through point (0, β8) and has a slope of 0.
x = β8
x = 0
y = β8
y = 0
Question 5(Multiple Choice Worth 1 points)
(02.04 MC)
A school system is reducing the amount of dumpster loads of trash removed each week. In week 5, there were 60 dumpster loads of waste removed. In week 10, there were 40 dumpster loads removed. Assume that the reduction in the amount of waste each week is linear. Write an equation in function form to show the amount of trash removed each week.
f(x) = β4x + 60
f(x) = 4x + 60
f(x) = β4x + 80
f(x) = 4x + 80
Question 6(Multiple Choice Worth 1 points)
(02.04 MC)
A computer manufacturer built a new facility for assembling computers. There were construction and new equipment costs. The company paid for these costs and made combined profits of $80 million after 4 years, as shown in the graph:
There is a graph of a line with Years on the x axis and Profits in millions on the y axis that passes through 1, negative 100 and 4, 80.
Which equation most closely represents the line depicted in the graph?
f(x) = 60x β 160
f(x) = β60x + 160
f(x) = β80x + 4
f(x) = 80x β 4

A student is running a 5-kilometer race. He runs 1 kilometer every 3 minutes. Select the function that describes his distance from the finish line after x minutes.
f of x equals negative one third x plus 5
f of x equals negative one fifth x plus 3
f of x equals one fifth x plus 5
f of x equals one third x plus 3
Question 8(Multiple Choice Worth 1 points)
(02.04 MC)
Choose the equation that represents the line that passes through the point (β1, 6) and has a slope of β3.
y = β3x + 3
y = β3x β 6
y = 3x β 3
y = 3x β 1

(02.04 MC)
Your friend has $100 when he goes to the fair. He spends $10 to enter the fair and $20 on food. Rides at the fair cost $2 per ride. Which function can be used to determine how much money he has left over after x rides?
f(x) = β2x + 70
f(x) = 2x + 70
f(x) = β2x β 70
f(x) = β30x + $100

Week Weight in ounces
0 3
1 6
2 9
3 12
y = 3x + 3
y equals one third times x plus 3
y = 3x + 12
y equals one third times x plus 12
