Does the depth of a river affect the amount of dissolved oxygen present in the water? Let x represent the depth of the river (in meters). Let y represent the concentration of dissolved oxygen (in parts per million, ppm). Suppose a study was conducted on various points along a river in a particular region: x 8.00 9.00 9.75 10.00 10.25 y 19 30 80 73 81 Find a for the equation of the least-squares line
