equation of the circle with center:?

Question

Find the equation of the circle with center (-1,7) and radius 2 .

a. x ^2 + 2x + y ^2 - 28y + 50 = 0
b. x ^2 - 2x - y ^2 - 14y - 48 = 0
c. x ^2 + 14x + 48 + y ^2 - 2y = 0
d. x ^2 - 14x + 48 + y ^2 - 2y = 0
e. x ^2 + 2x + y ^2 - 14y + 48 = 0

Answer 1

(x + 1) ² + (y - 7) ² = 4
x ² + 2 x + 1 + y ² - 14 y + 49 = 4
x ² + y ² + 2 x - 14 y + 46 = 0
Looks like a misprint in OPTION e

Answer 2

(x-(-1))^2+(y-7)^2=2^2=4
=>x^2+2x+1+y^2+49-14y=4
=>x^2+2x+y^2-14y+46=0
No answer is right!
