Solution

The plane passes through the point A(7, 8, 6).

∴ x1 = 7, y1 = 8, z1 = 6.

Since the required plane is parallel to the XY plane, direction ratios of normal vector will be a = 0, b = 0, c = 1(Z-axis).

Equation of a plane in Cartesian form is

a(x − x1) + b(y − y1) + c(z − z1) = 0

∴ 0(x − 7) + 0(y − 8) + 1(z − 6) = 0

∴ z − 6 = 0

∴ z = 6
