9
Step-by-step explanation:
The equation graphed from these points is y=3x+9, therefore the y-intercept is 9.
The answer is 16.
the girls shadow is 6 feet, and the trees is 24. you get to 24 by multiplying by 4. so do the same thing for the height. if the girls height is 4, multiply by 4 to get to the trees height. 4x4 is 16.
