The x-axis is the horizontal line
The y-axis is the vertical line
The axes intersect to form four infinite areas, or quadrants
Quadrant I is the top-right area
Quadrant II is the top-left area
Quadrant III is the bottom-left area
Quadrant IV is the bottom-right area
Points in Quadrant I will have positive x and y-coordinates
Points in Quadrant II will have a negative x and positive y-coordinate
Points in Quadrant II will have negative x and y-coordinates
Points in Quadrant II will have a positive x and negative y-coordinate
The open circles represent possible points along the axis
Answer:
B = (6, 4)
Step-by-step explanation:
You know that the midpoint is calculated as ...
M = (A +B)/2
Solving this for B, we find ...
2M = A + B
B = 2M - A
Filling in the coordinate values, we get ...
B = 2(5, -2) -(4, -8) = (2·5-4, 2(-2)+8)
B = (6, 4)

Answer:
Volume of tent = 189 ft^3
Step-by-step explanation:
triangle area = 1/2 x bh
a = 1/2 x 7 x 6
a = 1/2 x 42
a = 21
now find the volume with a=21 as B and h= 9ft (the length of the tent)
v=Bh
v = 21 x 9
v = 189 ft ^3
