Answer:
C (2,-4)
Step-by-step explanation:
You could graph the circle and then graph the points and see...
Or you could them in and see which point makes the left hand less than 4?
So if you wanted to draw it is a circle with center (2,-3) and radius 2.
If you want to do it the other way:
Plug in time!
(2,-5)?
(2-2)^2+(-5+3)^2
0^2+(-2)^2
0+4=4 so not this one
(2,-4)?
(2-2)^2+(-4+3)^2
0+1
1<4 so this one (you can also see this in the drawing:
The given fraction is:
We cannot take anything common from the numerator but from the denominator we can take out 2 as common because 2 is a factor of both the terms i.e. 2y and 10.
2y + 10 can be written as 2y +2(5) which can further be written as 2(y+5)
So, our fraction now becomes:
y+5 occurs in both the numerator and denominator and thus be cancelled out leaving behind:
Therefore, the given fraction in lowest term is equal to 1/2. So option B is the correct answer
