The graph at the right shows the rate of a scuba divers ascent to the surface. What does the y- intercept of the graph represent

50x5=$250

step-by-step explanation:

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)

if im not mistaking its

step-by-step explanation:  

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
