A quadrilateral is a shape with four sides. The perimeter of a quadrilateral is the sum of the lengths of its four sides.
The endpoints of this line segment are at (-2, -5) and (2, 5). What is the slope-intercept equation for this line?
| y = 1\(\frac{1}{2}\)x - 1 | |
| y = \(\frac{1}{2}\)x - 4 | |
| y = -1\(\frac{1}{2}\)x + 0 | |
| y = 2\(\frac{1}{2}\)x + 0 |
The slope-intercept equation for a line is y = mx + b where m is the slope and b is the y-intercept of the line. From the graph, you can see that the y-intercept (the y-value from the point where the line crosses the y-axis) is 0. 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, -5) and (2, 5) so the slope becomes:
m = \( \frac{\Delta y}{\Delta x} \) = \( \frac{(5.0) - (-5.0)}{(2) - (-2)} \) = \( \frac{10}{4} \)Plugging these values into the slope-intercept equation:
y = 2\(\frac{1}{2}\)x + 0
If the length of AB equals the length of BD, point B __________ this line segment.

bisects |
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.
The dimensions of this cube are height (h) = 1, length (l) = 3, and width (w) = 1. What is the volume?

The volume of a cube is height x length x width:
v = h x l x w
v = 1 x 3 x 1
v = 3
