1

The endpoints of this line segment are at (-2, 8) and (2, -2). What is the slope of this line?

46% Answer Correctly
-\(\frac{1}{2}\)
-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, 8) and (2, -2) so the slope becomes:

m = \( \frac{\Delta y}{\Delta x} \) = \( \frac{(-2.0) - (8.0)}{(2) - (-2)} \) = \( \frac{-10}{4} \)
m = -2\(\frac{1}{2}\)


2

What is 9a - 6a?

80% Answer Correctly
15a2
3a
3a2
54a2

Solution

To combine like terms, add or subtract the coefficients (the numbers that come before the variables) of terms that have the same variable raised to the same exponent.

9a - 6a = 3a


3

Solve 5b + 2b = -8b + 5y + 8 for b in terms of y.

34% Answer Correctly
-\(\frac{1}{7}\)y - 1\(\frac{1}{7}\)
12y + 8
-5y - \(\frac{1}{2}\)
\(\frac{3}{13}\)y + \(\frac{8}{13}\)

Solution

To solve this equation, isolate the variable for which you are solving (b) on one side of the equation and put everything else on the other side.

5b + 2y = -8b + 5y + 8
5b = -8b + 5y + 8 - 2y
5b + 8b = 5y + 8 - 2y
13b = 3y + 8
b = \( \frac{3y + 8}{13} \)
b = \( \frac{3y}{13} \) + \( \frac{8}{13} \)
b = \(\frac{3}{13}\)y + \(\frac{8}{13}\)


4

On this circle, a line segment connecting point A to point D is called:

46% Answer Correctly

circumference

radius

chord

diameter


Solution

A circle is a figure in which each point around its perimeter is an equal distance from the center. The radius of a circle is the distance between the center and any point along its perimeter. A chord is a line segment that connects any two points along its perimeter. The diameter of a circle is the length of a chord that passes through the center of the circle and equals twice the circle's radius (2r).


5

To multiply binomials, use the FOIL method. Which of the following is not a part of the FOIL method?

83% Answer Correctly

First

Odd

Inside

Last


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.
