3. The table shows how Beth’s total earnings at her
new job are related to the number of weeks she
has worked.
Which linear function could model Beth’s total
earnings as a function of weeks worked?
f (x) = 200x
f (x) = 600x
f (x) = 200x + 600
f (x) = 200x + 1400

6. The graph shows the function y = f (x). 8. A line passes through a point as shown in
the graph.
Which statement gives the correct domain and
range of the function shown?
The domain is all negative real numbers and
the range is all positive real numbers.
The domain is x ≤ 0 and the range is all
positive real numbers. Part A
The domain is x ≤ 0 and the range is y ≥ 1. Using the coordinates of the point shown in the
The domain is x ≤ 0 and the range is y ≥ 2. graph, what is the equation of the line in point-
slope form?
Part B
7. A line passes through the points (3,2) and (-3, 4) What is the equation of the line in slope intercept
form?
Part A
