I got the answer y=2x+21
I got this by counting the difference between the number in the chart
for example: 
-7 +2 =-5, which is the next number in the chart.
so the difference on the X side is +2 and the difference on the y side is +4.
So then we divide 4/2 and we get: 2, so m=2. 
Then to find the x intercept we have to add on to the chart until we get a 0 or a 1 on the x side. (so now you should have 1 on the x side and 21 on the y side) so then we just plug in all these numbers into the equation, y=mx+b
   so the answer should be y=2x+21. 
We know it is linear because the data in the chart can be converted into the equation y=mx+b (I just finished doing this for a gradpoint assignment)

All this question is asking you to do is multiply 65 and 7. The 7 comes from the amount of days in a week. The product of these numbers is 455.

0.5 x 4 = 2 feet / 2 feet in 4 seconds

New depth: 13 feet

0.4 x 3 = 1.2 feet / 1.2 feet in 3 seconds
13 - 1.2 = 11.8
