Given:
The equation of a line is
A perpendicular line on the given line passes through the point (4,-6).
To find:
The equation of the perpendicular line.
Solution:
We have,
On comparing this equation with slope intercept form , we get
So, the slope of the given line is -4.
We know that the product of slopes of two perpendicular lines is always -1.
The slope of the required line is and it passes through the point (4,-6). So, the equation of the line is
Therefore, the correct option is B.
