The endpoints of this line segment are at (-2, -8) and (2, 2). What is the slope of this line?
| 2\(\frac{1}{2}\) | |
| 3 | |
| \(\frac{1}{2}\) | |
| 1 |
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 = \( \frac{\Delta y}{\Delta x} \) = \( \frac{(2.0) - (-8.0)}{(2) - (-2)} \) = \( \frac{10}{4} \)If a = c = 5, b = d = 4, what is the area of this rectangle?
| 18 | |
| 35 | |
| 20 | |
| 32 |
The area of a rectangle is equal to its length x width:
a = l x w
a = a x b
a = 5 x 4
a = 20
Which of the following expressions contains exactly two terms?
binomial |
|
quadratic |
|
polynomial |
|

Which of the following statements about a parallelogram is not true?
the perimeter of a parallelogram is the sum of the lengths of all sides |
|
opposite sides and adjacent angles are equal |
|
a parallelogram is a quadrilateral |
|
the area of a parallelogram is base x height |
A parallelogram is a quadrilateral with two sets of parallel sides. Opposite sides (a = c, b = d) and angles (red = red, blue = blue) are equal. The area of a parallelogram is base x height and the perimeter is the sum of the lengths of all sides (a + b + c + d).
To multiply binomials, use the FOIL method. Which of the following is not a part of the FOIL method?

|
Inside |
|
First |
|
