5. 3,2 is not | 0,1 is | 9,-1 is not | 6,-2 is | 5,0 is not
6. The line is gonna be y= 1/3 - 2
Step-by-step explanation:
For 5 just plug in the numbers for x and y.
Distribute the .15 on the right side to get:
20 + .5x + 3 + .075x
Then, combine like terms (add numbers together and add x terms together):
.575x + 23
...and that's your final answer!
The formula is

r², and to find r, or radius, you divide the diameter by 2. Your radius is 12.5, so you just plug that into your formula, and you have pi(12.5)², and simplify that to pi(156.25) and then your answer is <span>490.873852123. You probably want to round to the nearest hundredth, I don't know if you have specific directions, but if so your final answer would be 490.87.</span>
