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.
Length = √area = √81 = 9
diagonal = √2 * side = √2*9 = 9√2
Given that AB = 16, BC = 5, and CD = 3, which is the length of secant DE?It might be useful to see ...
Y=-11. 2×-4 is -8, and -8-3 is -11.
