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.)
