Step-by-step explanation:
(3,5) and (-1,5)
slope= y2-y1 divided by x2-x1
so,
=5-5/-1-3
=0/-4
=0

Step-by-step explanation:
First image attached
The error was done in Step E, because student did not multiply
by the negative sign in numerator. The real numerator in Step E should be:

Hence, Step E must be
.
Second image attached
The error was done in Step C, because the student omitted the
of the algebraic identity
. Step C must be 
And further steps are described below:
Step D

Which according to the Quadratic Formula, represents a polynomial with complex roots. That is: (
,
,
)


(Conjugated complex roots)
Step E

Step F

11,339,800 is 11,340,000 rounded to the nearest whole number
The answer is 4.25
In the first step he never distributed the 1/12 to the 18. He only distributed to the 14
