need the variable and linear. model. please

2.29 During a recent solar car race, you gathered the following data on daily power consumption and total mileage traveled. There is believed to be a linear relationship between power and distance, that is, of the form for some unknown values of m and b, along with some random error term. In a statistics class, you would generate a least-squares regression line that minimizes the sum of squared difference between the observed distances and the predicted distances, based on the linear model, that is, Suppose instead you want to minimize the sum of the absolute deviations between the observed distances and predicted distances, that is, What values of m and b will give this? Note that both m and b should be nonnegative
