Hello Tryphena,

Nice video!  I like the artistry, music, and content!

My only suggestion is...
For your second problem, where you use the equation y=(1/2)x+7...you
write it as "y=1/2x+7" makes it appear as though the variable "x" is in the denominator
of the fraction, i.e. 1/(2x)...I suggest you either write it with the "1/2" in parentheses
(as I have above), or just with the "1/2" clearly as a coefficient of "x"...like this:
1
-- x.
2

Keep up the great work in mathematics!   :-)

Best wishes.
