In the plane, we have
everywhere. So in the equation of the sphere, we have
which is a circle centered at (2, -10, 0) of radius 4.
In the plane, we have
, which gives
But any squared real quantity is positive, so there is no intersection between the sphere and this plane.
In the plane,
, so
which is a circle centered at (0, -10, 3) of radius .
In the given graph :
y - intercept of the line (c) is :
- 2
let's find slope (m) :
now, let's equate it with general equation to find the equation of line,
- y = mx + c
m = -2
c = 2
therefore, the equation of line will be :
- y = -2x + 2
