I think A which is 4in but not sure
The equation of the line with slope m and passing through the point
is

Since m=6 and the coordinates of the point are (8,3), then the equation is

Answer: correct choice is B.
Isolate z by itself:

To simplify variables with powers, subtract the smaller power from the bigger power:


The exponent will be
-3.
Answer: Correct
Step-by-step explanation:
The conclusion is valid. Since
and
, we know that ABCD is a parallelogram because it has two pairs of parallel sides. Also, since
, we know that ABCD is a parallelogram with a pair of consecutive congruent sides, making it a rhombus.
