Area of circle: 

Answer:
-19
Step-by-step explanation:
plug in 2 for x.
Answer:
B. y= (2x/3)+4
Step-by-step explanation:
i picked a point and plugged the x and y into the equation to see if it would work
(example:
)
then i did the same thing with a different point on the graph to make sure it was correct :)
A.) (-2,-4)
(7+3)/2=5, (10+2)/2=6
(-7+5,-10+6)
(-2,-4)
b.)r^2=244
10^2+12^2=244
r=2(61)^(1/2)
c.)(x+2)^2+(y+4)^2=244
