The endpoints of this line segment are at (-2, 2) and (2, -6). What is the slope of this line?

46% Answer Correctly

	3
	-\(\frac{1}{2}\)
	-2
	\(\frac{1}{2}\)

Solution

The slope of this line is the change in y divided by the change in x. The endpoints of this line segment are at (-2, 2) and (2, -6) so the slope becomes:

m = \( \frac{\Delta y}{\Delta x} \) = \( \frac{(-6.0) - (2.0)}{(2) - (-2)} \) = \( \frac{-8}{4} \)
m = -2

The dimensions of this cylinder are height (h) = 3 and radius (r) = 4. What is the volume?

62% Answer Correctly

	96π
	48π
	147π
	288π

Solution

The volume of a cylinder is πr²h:

v = πr²h
v = π(4² x 3)
v = 48π

Simplify (y + 2)(y + 5)

62% Answer Correctly

	y² + 7y + 10
	y² - 3y - 10
	y² - 7y + 10
	y² + 3y - 10

Solution

To multiply binomials, use the FOIL method. FOIL stands for First, Outside, Inside, Last and refers to the position of each term in the parentheses:

(y + 2)(y + 5)
(y x y) + (y x 5) + (2 x y) + (2 x 5)
y² + 5y + 2y + 10
y² + 7y + 10

A trapezoid is a quadrilateral with one set of __________ sides.

70% Answer Correctly

	parallel
	equal length
	equal angle
	right angle

Solution

A trapezoid is a quadrilateral with one set of parallel sides.

A(n) __________ is two expressions separated by an equal sign.

76% Answer Correctly

	equation
	expression
	problem
	formula

Solution

An equation is two expressions separated by an equal sign. The key to solving equations is to repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the equal sign and the answer on the other.
