Take the point P on the image of the linear function y = - x + 3, make PA perpendicular to the x-axis and Pb perpendicular to the y-axis. If the s rectangle paob = 9,4, how many points can be found It is helpful for the responder to give an accurate answer

Take the point P on the image of the linear function y = - x + 3, make PA perpendicular to the x-axis and Pb perpendicular to the y-axis. If the s rectangle paob = 9,4, how many points can be found It is helpful for the responder to give an accurate answer

S rectangle paob = XY product absolute value = 9 / 4
According to the meaning constructors y = 9 / 4x (and y = - x + 3, the solution is that the image is tangent in the first quadrant, that is, there is a common point) and y = - 9 / 4x (there are two intersections with y = - x + 3, obviously)
There are three intersections between them and the linear function y = - x + 3
So there are three such points
