A student trаins а lineаr regressiоn mоdel using gradient descent. One feature is hоuse size measured from 500 to 5,000 square feet, while another feature is number of bedrooms measured from 1 to 6. The student does not scale the features, and gradient descent takes a long time to converge. Why is feature scaling important in this situation?
