Answer:
-3/4 is plotted 3 little tabs left of 0
5/4 is plotted 1 little tab right of 1
If you are trying to figure out the distance between the top of the tree and the end of the shadow, use a^2 + b^2 = c^2 where c is the hypotenuse and a and b are the legs of the right triangle.
5^2 + 4^2 = c^2
25 + 16 = c^2
41 = c^2
c = √41 = 6.4 meters
This may be wrong but I'm going to go with B. 1/7 x 9/10
Hope this helps! ( Probably didn't help in any way but I tried).
Answer:
a) yx=63
b) y=3

7(9)=k
63=k
b)
y(21)=63
y=63/21
y=3
