Answer:
Trina is closer
Step-by-step explanation:
Trina is closer to the surface of the earth because -85.6 vs 87.9
85.6 ft is closer by 2.3 ft.
Y varies with x
so y/ x = constant
so, y1/x1 = y2/x2
6/9 = 18 / x2
so x2 = ( 9*18)/6
x2 = 27
another solution
y varis with x
y inceased by 3 times
so x must increase 3 time of the intial value
x(new) = 9*3 = 27
