The endpoints of this line segment are at (-2, 6) and (2, -6). What is the slope of this line?
| -2\(\frac{1}{2}\) | |
| -1 | |
| -3 | |
| 3 |
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, 6) and (2, -6) so the slope becomes:
m = \( \frac{\Delta y}{\Delta x} \) = \( \frac{(-6.0) - (6.0)}{(2) - (-2)} \) = \( \frac{-12}{4} \)What is 6a - 7a?
| a2 | |
| 42a2 | |
| -1a | |
| -1 |
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.
6a - 7a = -1a
Order the following types of angle from least number of degrees to most number of degrees.

An acute angle measures less than 90°, a right angle measures 90°, and an obtuse angle measures more than 90°.
Breaking apart a quadratic expression into a pair of binomials is called:
normalizing |
|
squaring |
|
deconstructing |
|
factoring |
To factor a quadratic expression, apply the FOIL (First, Outside, Inside, Last) method in reverse.
Which of the following expressions contains exactly two terms?
polynomial |
|
monomial |
|
quadratic |
|
binomial |
A monomial contains one term, a binomial contains two terms, and a polynomial contains more than two terms.
