7) Suppose y = 10, 4, 8 when x is 1,1,2. Our model uses parameters theta=1,1 and when we run it using x=1,1,2 it predicts y = 9,5,8. We then back calculate dloss/dtheta = 2,-1. a) In what direction should we move theta to try to reduce loss? + b) Assuming loss was defined as the sum of the squared errors, approximately what would be the sum of the squared errors in out next prediction if we change theta to 1.001,1.002 ?-e %3!

9. Let y=3x+2 a) typically we write points in this scenario as (x,y), not (y,x), why is that? b) on a horizontal axis, represent 3 things: x=-2, x=4, and Δx=4-(-2). c) on a vertical axis, represent 3 things: y=-4, y=14, and Δy=14-(-4). d) draw a sketch of y=f(x) which includes the points (-2,-4) and (4,14). Mark and label Δx and Δy for those two points on this graph. e) calculate that rate, then write the change equation for x and y f) if the change in x is 2, what is the change in y? g) if the change in y is -12, what is the change in x? h) if we swapped x and y (with x on the vertical axis so x=g(y)), what would the rate be?
