Answer:
<u>Direct Variation is a relation that is of the form y = mx.</u>
and
<u>Partial Variation is a relation that is of the form y=mx+b</u>
Explanation:
This is a simple way to see the difference between them.

Graph A is a linear function, while Graph B is an exponential funtion.
4x is the answer for this one
y² = 8y - 15 (alternate angles are equal)
y² - 8y + 15 = 0
(y - 5)(y - 3) = 0
y = 5 or 3
x + 8y - 15 = 180 (angles in a straight line add up to 180)
when y = 5
x + 40 - 15 = 180
x = 155°
when y = 3
x + 24 - 15 = 180
x = 171°
