Answer:
C. 
Step-by-step explanation:
To find slope using coordinates, use the formula above.

Now, using the
formula, plug in
as
(slope) and either coordinate as the
and
values. It looks like this:

To solve for
, continue to use PEMDAS.

Now use
and
to solve for your equation:

The answer is C.
Answer:
c
Step-by-step explanation:
Answer:
-10
Step-by-step explanation:
Solving for y gives ...
20y = 2x +6
y = 2/20x +6/20 = 1/10x +3/10
The slope of the given line is the coefficient of x: 1/10. The slope of the perpendicular line is the opposite reciprocal of this: -1/(1/10) = -10.
The perpendicular line has a slope of -10.
