Answer:
The slope is 7/7 or 1.
Step-by-step explanation:
Find any two points on the line. I chose (0,7) and (-7,0).
Put rise over run.
7-0
———
0 – -7
this would equal 7/7 which simplifies to 1.
Hope this helped!

Answer:
6.25 pi cm^2
Step-by-step explanation:
The formula for circumference is
C = 2*pi*r
We know the circumference is 5 pi
5 pi = 2 * pi *r
Divide each side by pi
5 pi/pi = 2 * pi *r/pi
5 = 2r
Divide by 2
5/2 = 2r/2
2.5 = r
We need to find the area of the circle
The area is given by
A = pi * r^2
= pi * (2/5)^2
= pi *6.25
= 6.25 pi cm^2
