Step-by-step explanation:
A marble is a sphere, and the volume of a sphere can be found using:

We need to find the radius, and we know that the radius is 1/2 of the diameter
r=d/2
r=17/2
r=8.5
Now we can substitute 8.5 in for r, and 3.14 in for pi




Answer:
b) y = -2/3 + 1
Step-by-step explanation:
The format for the equation is y = mx + b
(m is the slope, and b is the y intercept)
Slope is rise over run (the units the line moves up and the units the line moves to the right)
In this case, the slope is: -2/3 because it goes down 2 and to the right 3.
The y intercept is 1.
This makes our equation:
y = -2/3 + 1
