The line through the point (a, b) and parallel to the line Ax + By + C...
Explanation:
Given:
Point (a, b) and a line Ax + By + C = 0, which is parallel to the required line.
Formula:
The equation of a line parallel to Ax + By + C = 0 passing through the point (a, b) is given by A(x - a) + B(y - b) = 0.
Explanation of the formula:
- A and B are the coefficients of x and y in the given line equation.
- (a, b) is the given point through which the line passes.
- The formula represents the equation of a line parallel to the given line and passing through the given point.
Substitute the values:
Substitute the values of A, B, a, and b in the formula:
A(x - a) + B(y - b) = 0
=> A(x - a) + B(y - b) = 0
Final Answer:
Therefore, the line through the point (a, b) and parallel to the line Ax + By + C = 0 is represented by the equation A(x - a) + B(y - b) = 0. So, the correct answer is option 'D'.
