Slope = (y2 - y1)/(x2 - x1)
Slope = (8 - 0)/(3 - 1)
Slope = 8/2
Slope = 4

Answer:
B)The volume of the pyramid is 1/3 the volume of prism
Step-by-step explanation:
We are given that
Bases of rectangular pyramid and rectangular prism are same
Height of both rectangular pyramid and rectangular prism are same.
We know that
Volume of rectangular pyramid =
Where b=Area of base
Volume of rectangular prism=
Where b=Area of base
Volume of rectangular pyramid=
volume of rectangular prism
Hence, the volume of pyramid is 1/3 times the volume of volume of rectangular prism.
Option B is true.
Let x = number of 5 cent coins.
Then there are (x+2) 10 cent coins.
Let y = 20 cent coins.
Total coins: x+(x+2)+y = 30
2x+y=28
y = 28-2x (1)
Total value: 0.05x + 0.1(x+2) + 0.2y = 3.80
0.15x + 0.2y + 0.2 = 3.80
0.15x + 0.2y = 3.60 (2)
Substitute (1) into (2).
0.15x + 0.2(28-2x) = 3.60
-0.25x + 5.60 = 3.60
2.00 = 0.25x
8 = x
From (1), obtain y = 28 - 2(8) = 12
Answer: (x+2) = 8+2 = 10
