You start at 0 on the unit circle the cos of 0 =1, but at cos 0 there is no angle at all so there is no y value so at cos 0 y=0, 180 is the opposite direction of the starting point which is 0 so the x value of cos180= -1 but there is still no upward or downward angle ie.. y value. so the y value = 0 at 0 and 180. answer is 0
ANSWER

EXPLANATION
Recall that,

That is why

is equivalent to

This implies that,

This is the same as,

When we are dividing by

we move the decimal point backwards two times.
This implies that,
Simplified, it"s y=-3/2x+22.5
