y=mx + c. In our study, y = price of the house, m = gradient of the line, z = distance from the town centre and c = the intercept of the y axis. In effect, c is the price of an imaginary house near the town centre and m is the price increase per km. Our job is to find the value of m and c because these are SPECIFIC to Oldham. Other towns would have other values for m and c.
