Answer:
The correct option is c.
Step-by-step explanation:
The slope intercept form of a line is

Where, m is the slope of the line and b is the y-intercept.
The given equation is

The slope of line is
and the y-intercept of line is -5.
The product of slopes of two perpendicular lines is -1.



The point slope form of a line is

The slope of required line is -2 and the line passing through the point (2,-7). The equation of the line is

Therefore option c is correct.
