Answer:
y = -3/1x + 2
Step-by-step explanation:
1. Find the slope
The points I will use are (-1,5) and (0,2), where x1 = -1, y1 = 5, x2 =0, and y2 =2.
y2-y1/x2-x1
2-5/0-(-1) = -3/1
2. Find the y-intercepy
y = mx + b
You can use any x or y point. I'll use (-1,5)
m= slope, which is -3/1
5= -3/1(-1) +b
5= 3 + b
Subtract 3 from 5 and 3 to get 2=b.
3. Rewrite in slope-intercept form
y = -3/1x + 2
The SA is correct but volume is off. 4/3 times pi times radius cubed is 904.7787. When making your ratio you would divide the SA by the volume to get a ratio that is about 1 to 2.
Answer: D
Step-by-step explanation: +2 would be an upwards translation
A= 0.25 or 1/4
