Question

Im not very sure how tot answer this i need help fast

Answer 1

First see if there is a constant rate of change...

(344.8-346)/(2-0)=-0.6

(343-344.8)/(5-2)=-0.6

So the rate is constant which means this is just a line of the form y=mx+b

m=-0.6 and since we see that (0,346) we know the y-intercept, "b", is 346 so our line is:

y(x)=-0.6x+346

y(4)=343.6 ft

y(9)=340.6
