Find the equation of the circle centre (2. 3) which passes through the y - intercept of the line 3x - 2y + 6 = 0
To find the equation of the circle with center (2, 3) that passes through the y-intercept of the line 3x - 2y + 6 = 0, we need to follow these steps:
To find the y-intercept, we set x = 0 and solve for y:
3(0) - 2y + 6 = 0 -2y + 6 = 0 -2y = -6 y = 3
So the y-intercept of the line is (0, 3).
The radius of the circle is the distance between the center (2, 3) and the y-intercept (0, 3):
r = sqrt((2 - 0)^2 + (3 - 3)^2) = sqrt(4) = 2
So the radius of the circle is 2.
The equation of a circle with center (h, k) and radius r is:
(x - h)^2 + (y - k)^2 = r^2
Plugging in the values we found, we get:
(x - 2)^2 + (y - 3)^2 = 2^2
Simplifying, we get:
(x - 2)^2 + (y - 3)^2 = 4
So the equation of the circle with center (2, 3) that passes through the y-intercept of the line 3x - 2y + 6 = 0 is (x - 2)^2 + (y - 3)^2 = 4.
