so 6, -4 thats 2?
Vocaloid:
be careful with signs
6 - (-4) = 10 not 2
so 10/2 = 5 = your ans

Vocaloid:
period = difference between two peaks (highest point) or two troughs (lowest point)

Vocaloid:
so the period is just 15 - (-5) = 20 if I'm reading correctly
princeevee:
so it's 20?
Vocaloid:
yes

princeevee:
so 4 and -4
princeevee:
8/2 is 4
princeevee:
4 is the cosmic number.
Vocaloid:
here they are asking for the minimum not the altitude
so it's just the lowest value the graph reaches (-4) = your answer
princeevee:
wait, 4 or -4?

-4
minimum means lowest

i'm still a bit stumped
Vocaloid:
for a horizontal line the equation is
y = ___
where the y-value crossed by the line is inside the blank
Vocaloid:
for example, if a horizontal line crosses 3 like so:
|dw:1515537192422:dw|
the equation is y = 3
Vocaloid:
now, apply this logic and find the equation for the below horizontal line:|dw:1515537223981:dw|

Vocaloid:
the line is crossing 0
making the equation y = __
fill in the blank
princeevee:
0?
Vocaloid:
good so y = 0 = your answer.
princeevee:
okay, thank you
