Math, Please help me!!!!!?

Math problem: An oceanographer measured the length, in meters, of a deepwater wave and its speed, in meters per second. The results are shown in the following table.

Wave Length (m) Speed (m/s)

100 14.5

125 13.4

130 15.9

175 16.9

210 21.8

350 24.5

400 24.8

(a)

Find the equation of a linear regression line for the data where wave length is the independent variable, x, and speed is the dependent variable. (Round your numerical values to two decimal places.)

ŷ =

(b)

Using the equation from part (a), estimate the speed (in meters per second) of a wave that is 200 m long. (Round your answer to one decimal place.)

    If this is for your math homework, I will not give you the answers to that. You should be answering that yourself and not ask random people on Yahoo answers the answers to your homework.

    a. ŷ= 0.04X + 10.45 (I used an online calculator)

    b. ŷ= 0.04*200 + 10.45= 18.5 m/s

    slope 0.04

    intercept 11.48

     19.48

    You might want to look into doing this in Excel.
