Answer:
-3/4
Step-by-step explanation:
First, pick two coordinates.
(0,2) and (4,-1)
Then do the rise over run or y/x.
The y is 3 and the x is 4. That is 3/4.
Since the line is going down, it will be negative.
The answer is -3/4.
Exact value of x will be 8 x sin(60)
Exact value of sin 60 = √3/2
So √3/2 x 8= 8 √3/2
Can be simplified to 4 √3
