Glaucoma is the second leading cause of vision loss world-wide. High intraocular pressure (pressure inside the eye)

Question:

Glaucoma is the second leading cause of vision loss world-wide. High intraocular pressure (pressure inside the eye) almost always accompanies vision loss. It is postulated that the high pressure damages a subset of cells in the eye that are responsible for vision. One investigator theorizes that the relationship between vision loss and pressure can be described as

Where VL is percent vision 1oss, P is intraocular pressure (mm Hg), t is time (years), and k and A are constants. Using the data below from three patients, estimate the constants k andA.
