Mark against the A. x + y + z = 3
B. x + y + z = 6
C. x + y + z = 9
D. x + y + z = 4
Given: A(2, -3, 7) is a point on the plane making equal intercepts on the axes.
Formula Used: Equation of plane is where (x, y, z) is a point on the plane and a, b, c are intercepts on x-axis, y-axis and z-axis respectively.
Let the equation of the plane be
Here a = b = c = p (let’s say)
Since (2, -3, 7) is a point on the plane,
p = 6
Therefore equation of the plane is
x + y + z = 6
