Answer:

Explanation:
We are given that an equation

We have to find the equation of a line that passes through the point (2,7) and perpendicular to given line.
Differentiate w.r.t x

Using:

When two lines are perpendicular then
Slope of a line=

Slope of perpendicular line=

The equation of a line passing through the point (

with slope m is given by

Using this formula
The equation of perpendicular line with slope -4 and passing through the point (2,7) is given by



Hence,the equation of the line which is passing through the point (2,7) and perpendicular to the given line is given by
