Write the equation of the plane whose intercepts on the coordinate axes are 2, -4 and 5 respectively.

Given :


X – intercept, a = 2


Y – intercept, b = - 4


Z – intercept, c = 5


To Find : Equation of plane


Formula :


If a, b & c are the intercepts made by plane on X, Y & Z axes respectively, then equation of the plane is given by,




Multiplying above equation throughout by 40,



20x – 10y + 8z = 40


10x – 5y + 4z = 20


This the equation of the required plane.
