(Python) Write the Multiple Linear Regression Function with the given dataset data2.txt. The given data2 consists of x, y(independent variable), z(dependent variable) data. For example, 2104,3,399900 // 2104 = x, 3 = y, 399900 = z 1600,3,329900 // 1600 = x, 3 = y, 329900 = z. find Slope(Gradient), Bias(intercept), Score of the regression graph?(25%)

( For score, use model.score(x,y) to quantify your accuracy )

Contents of data2.txt are given below
