NEED HELP! student is interested in the depth of the water off the end of the local pier. Starting at midnight, he measures the depth of the water every three hours for an entire day and records the results in the table.

The equation of the least-squares regression line is
ŷ = 13.0 – 0.259x, where ŷ is the depth of the water and x is the number of hours past midnight. Which shows the residual plot?

Which undefined geometric term is described as a location on a coordinate plane that is designed by an ordered pair (x,y) ?
