Answer: -1/2
Step-by-step explanation: to find slope, use the equation (y2-y1) / (x2-x1)
(-6 - -3) / (7 - 1)
-3 / 6
= -1/2
Easy and fast way to do it:
Go to google and type, " volume of a cone calculator" and type in the radius and height.
3/2+3/2=3 That is a good equation because all of the characters are bigger than one 3/2 is equal to 1.5 and 3 is greater than 1
A rational number is a number that can be written in the form:

Where p and q are coprimes. We are asked for finite sets, we can rule out options 3 and 4. In the set in option 2 the first element is:

This number cannot be written a ratio. We can rule out option 2.
All the elements in the set from option 1 can be written in the form p/q.Thus, the answer is the first option.
