Answer: I don’t think there is such a line. A Line that passes through the point (3,-9) must have a positive slope, unlike the line y=-5x-2, which has a negative slope. If a line where to go through (3,-9), is would intersect the line you presented.
Answer:

Step-by-step explanation:
27 is a perfect cube for
and 729 is a perfect cube for 
now you can pull out the numbers from under the root, for t (divide the exponent by 3)

now simply to 
Answer:
5√3 / 2
Step-by-step explanation:
tan 30 = ( 5 / 2 ) / y
1 / √3 = 5 / 2y
2y = 5√3
y = 5√3 / 2
