The endpoints of this line segment are at (-2, 2) and (2, -2). What is the slope of this line?
| -2\(\frac{1}{2}\) | |
| -1 | |
| 3 | |
| -1\(\frac{1}{2}\) |
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, -2) so the slope becomes:
m = \( \frac{\Delta y}{\Delta x} \) = \( \frac{(-2.0) - (2.0)}{(2) - (-2)} \) = \( \frac{-4}{4} \)If the length of AB equals the length of BD, point B __________ this line segment.

A line segment is a portion of a line with a measurable length. The midpoint of a line segment is the point exactly halfway between the endpoints. The midpoint bisects (cuts in half) the line segment.
On this circle, line segment AB is the:
diameter |
|
radius |
|
circumference |
|
chord |
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).
A trapezoid is a quadrilateral with one set of __________ sides.
equal angle |
|
equal length |
|
parallel |
|
right angle |
A trapezoid is a quadrilateral with one set of parallel sides.
What is the circumference of a circle with a diameter of 9?
| 18π | |
| 9π | |
| 22π | |
| 26π |
The formula for circumference is circle diameter x π:
c = πd
c = 9π
