A direct variation is described by an equation of the form y = kx, where k = 0.
True.
False.
Suppose you earn $188 for working 16 hours. What direct variation equation correctly relates your earnings to the number of hours worked?
x = 11.75y
y = 0.08x
x = 0.08y
y = 11.75x
What linear equation matches the following graph?
f(x) = 1/4x + 7
f(x) = 2/3x + 4
f(x) = 2/3x - 4
f(x) = 7/8x - 6
A hot air balloon was at the height of 80 feet above the ground when it began to ascend. The balloon then climbed a rate of 20 feet per minute. Make an algebraic equation for a sequence that can be used to find the height, h, of the balloon after t minutes. Use your equation to find the height, in feet, of the hot air balloon after climbing for 8 minutes.
240 feet.
300 feet.
900 feet.
100 feet.

What is the slope of the linear function graphed below?
7/9.
4/5.
1/2.
9/7.
Find the next three terms in this arithmetic sequence:
13, 25, 37, 49, . . .
61, 73, 85.
56, 64, 72.
90, 100, 110.
None of these.
Suppose y varies directly as x. If y = 15 when x = 2, find when y when x = 6.
When x = 6, y = 890.
When x = 6, y = 66.
When x = 6, y = 45.
When x = 6, y = 40.
Find the root of 0 = 9.5x + 5. Round to the nearest thousandth.
x = 0.526.
x = -0.526.
y = -0.526.
x = 9.55.
Starr's class is selling candy bars. Starr's class paid $105 for the candy bars, and they are selling each candy bar for $1. The function y = x - 105 represents their profit y for each candy bar for each candy bar sold x. Find the zero and choose the correct description of what it means in this situation.
105; Once they have sold 105 candy bars, they will have earned back their initial investment.
105; Starr's class started with $105.
1; Starr's class is selling each candy bar for $1.
