Point a is the intersection of the image with positive scale function y = 2x and inverse scale function y = 8 / X in the first quadrant (there are two questions at the end. Let's look at the supplementary questions.) (1) Finding the coordinates of point a (2) If the line y = 4 / 3x + B passes through point a and intersects with the x-axis at point C, calculate the coordinates of B and point C Dear friends, I am lazy=

Let 2x = 8 / x x > 0, x = 2, y = 2x, y = 4, a (2,4)
The straight line y = 4 / 3x + B passes through point a, brings a (2,4) in, and obtains B = 4 / 3
Let 4 / 3x + 4 / 3 = 0, then x = - 1, and the coordinate of point C (- 1,0)
