To find: The equation of the line tangent to the circle at the point
Answer to Problem 57E
The equation of the line tangent to the circle at the point
Explanation of Solution
Given information: The circle of the radius is
Calculation:
The formula for the slope of the line that passes through the two points is given by,
Substitute
The tangent line is tangent to the radius line, so it slope will be as follows.
The point slope equation of line is given by,
Substitute
Therefore, the equation of the line tangent to the circle at the point
