Question

The center of a circle lies on the line y=6x+2 and is tangent to the X axis at (-2,0) what is the equation of the circle in standard form?

Answer 1

(x + 2)^2 + (y + 10)^2 = 100

Explanation:

+2.....+10..100

exactly that

Answer 2

(x+2)^2 + (y+10)^2 = 100

Explanation:

y = 6x + 2

Z(-2,0)

x = -2

y = 6 x (-2) + 2

y = -12 + 2

y = -10

M(-2, -10)

r = 0 - (-10) = 10

(x + 2)^2 + (y + 10)^2 = 100
