If in standard form you mean slope intercept form, then you are looking to create an equation that looks like this:
y = mx + b
So you need to move around the numbers whilst keeping both sides equivalent.
3x - 9 = 7y
7y = 3x - 9
y = (3x)/7 - 9/7
Your answer should look like this:
y = (3x)/7 - 9/7
If this is not what you meant by standard form please comment and I will see if I can adjust the answer.

and
Hence,
Hence
Answer:
C ≈ 22.1°
Step-by-step explanation:
The law of cosines formula is given. Solving it for C, we find ...
C = arccos((a^2 +b^2 -c^2)/(2ab))
where a and b are the sides adjacent to the angle.
Then we have ...
C = arccos((14^2 +19^2 -8^2)/(2·14·19)) = arccos(493/532)
C ≈ 22.1°
