Ab ⊥ BD, CD ⊥ BD, B and D are perpendicular feet, ab = 2, CD = 3, P is the moving point of BD, let Pb = x, BD = y, make P and a, B, C, D form two similar triangles, Finding the function analytic expression of Y with respect to X Make point P form two similar triangles with a, B, C and D respectively

ABP is similar to CDP, so AB: CD = BP: DP, that is 2:3 = x: (Y-X), and y = (5 / 2) X
To illustrate, since there is no diagram, we can only give you one situation as a reference,
