Point a is an image with positive scale function y equal to 2x and inverse scale function y equal to 8 / X. find the coordinates of point a at the intersection of the first quadrant. Solve the equations y = 2x, y = 8 / x, and get x = 2, y = 4 or x = - 2, y = - 4 ∵ the intersection of point a in the first quadrant ∵ A is (2,4) [2] if the line y is equal to 4 / 3] x + B passing through point a and connecting with X axis
