= 1. Given the following data, develop a Python program that uses a linear regression to model the relationship: angle : (slope)*voltage + (intercept) angle (radians) = [-1.57, -1.26, -0.94,-0.63, -0.31, O., 0.31, 0.65, 0.96, 1.23, 1.52] voltage (volts) = [1.176, 1.648, 1.874, 2.175, 2.438, 2.503, 2.925, 3.067, 3.450, 3.686, 4.014] Please produce the following: (a) Print out the slope, intercept and r2 value of the relationship with appropriate units. (b) Plot the raw data and line-of-best-fit on a single plot
