To
understand this picture 2 cones that are stacked one on top of
another. A double-napped cone is created when a generator is rotated
about a fixed vertical axis. A line is created when the cone is cut
by a plane containing the generator. Please see the attachment to
help you understand this.

hope this helps, Regards.
The equation of line perpendicular to given line through (-6,7) is:

Further explanation:
Given equation of line is:

The co-efficient of x is the slope of given line.
Let m1 be the slope of given line
and
m2 be the slope of line perpendicular to given line
Then

Product of slopes of perpendicular lines is -1

The equation of new line can be written as:

Putting m2

To find the value of b, we will put (-6,7) in equation

Putting the values of b and m in general equation
