Question

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

a
b
(x + 1)2 + (y-2) - 7
(x - 2)2+(y+1) - 49
(x+1)+(y-2) - 49
(x-1) + (y+2) = 49

Answer 1

(X+1)^2+(y-2)^2=49

Explanation:

Standard Equation of a circle:
`(x-h)^(2) +(y-v)^(2)`=
`r^(2)`

Center: (-1,2)

Radius: 7

Equation would be:
`(x+1)^2+(y-2)^2=49`
