The line graph
First, consider the following points on the graph.


First, calculate the slope.



undefined
Since, the slope is undefined; we simply consider only the value of x.
The line equation is:

Its D because when you use some graph paper point A and point B are 6 units away from each other
Divide 6 by 3
3 goes into 6, 2 times so one apple costs $2
Answer:
Centre: (4,3)
Radius: 2sqrt(2)
Step-by-step explanation:
h = -8/-2 = 4
k = -6/-2 = 3
4² + 3² - 17 = r²
r² = 8
r = sqrt(8) or 2sqrt(2)
sqrt: square root
