The answer is <em>x = 3</em>, because x = 3 has an undefined slope (m = 0 or is imaginary), and it contains 3, 0 which makes 3, 0 a solution.
Answer:
Equation:
Intersection:
Step-by-step explanation:
We are asked to write an equation of the sphere with center center and radius 4.
We know that equation of a sphere with radius 'r' and center at is in form:
Since center of the given sphere is at point , so we will substitute
,
,
and
in above equation as:
Therefore, our required equation would be .
To find the intersection of our sphere with the yz-plane, we will substitute in our equation as:
Therefore, the intersection of the given sphere with the yz-plane would be .
