step-by-step explanation:

it would be 9 because when it is the nine is over five so that would mean it rounds up to 90 or 9

  or  

sin y = 7/q

7 is the opposite side length, q is the hypotenuse

tan y = 7/r

7 is the opposite side length, r is the adjacent side length

using sohcahtoa ^^^^

cos y = adjacent/hypotenuse

cos y = r/q

parallel lines have the same slope. so if the green line has a slope of -4, the slope of the red line is also -4.
