Answer:
y=3x+5
Step-by-step explanation:
This would be a graph, a function is a straight line while a graph can be a scatter plot or something similar
I did this in my head but the answer is $36 45/5 is 9 9*4 is 36. And if you add another it totals to 45. Thus the answer is $36.
(3,2) because you go 2 to the left and up 3
The highlighted sector is exactly 3/4 of the circle area, because 
is 3/4 of 
which is a complete rotation.
Since you are given the radius, you can compute the area as
So, 3/4 of this area would be 
squared cm.
The remaining sector, of course, is 
squared cm.
