Graph the circle which is centered at (-3, -2), and which has the point (-3, -9) on it.
1 answer:
Answer:
(x+3)² + (y+2)² = 49
Step-by-step explanation:
To graph the circle that has centre of (-3,-2) with a point (-3, -9) on it.
First, let us write the equation of the circle
The equation is expressed as;
(x-a)² + (y-b)² = r²
(a, b) is the centre
r is the radius
r = √(-9-(-2))² +(-3-(-3))²
r = √(-9+2)² +(-3-(-3))²
r = √(-7)²
r = √47
r = 7
Get the equaton
(x-(-3))² + (y-(-2))² = 7²
(x+3)² + (y+2)² = 49
This gives the required equation
