Answer:
The usual way to draw a 3-D grid can be seen below.
The positive z-axis points upwards
The positive y-axis points to the right
The positive x-axis points towards you, or to the front.
And the notation for a point in 3-D is (x, y, z)
In this case, our point is (-3, -2, 3)
Then the location of the point can be described as:
So the x-value is -3, which means that the point is 3 units behind the origin.
The y-value is -2, which means that the point is 2 units at the left of the origin
The z-value is 3, which means that the point is 3 units above the origin.
Since a pentagon has 5 sides, you would divide the perimeter by the number of sides.
641.5/5 = 128.3cm
Therefore, the length of one side of the pentagon is 128.3cm.
When a line is perpendicular to another line with a given slope, you can use the given slope of the original line to find the slope of the perpendicular line. All you need to do is flip the reciprocals. Since the slope of the given line is -1/8x, the slope of the perpendicular line would be 8x. Since there is only one line with a slope of 8x in the answer choices, your answer would be:
a. y=8x+13
