The answer to your question is 8mi. I just divide the circumference by pi to find your diameter.
Answer:
Slope = -2
Step-by-step explanation:
x1 y1 x2 y2
(-1 , 9) (2 , 3)
Slope = <u>y2 - y1</u>
x2 - x1
<u>3 - 9 </u>= <u> -6 </u>
2 -(-1) = 3
= -2
Subtract 45 on both sides of the equation, then divide both sides of the equation by 2. Your answer should end up being e=-15
Finding the slope, you get (-1-(-5))/(3-0)=4/3. For finding the slope, you can also just count the rise and the run, then divide them. For exampe, (3,-1) is 4 units higher and 3 units to the left, so the slope is 4/3. Also, looking at the graph shows you that the y-intercept is just (0,-5).
