Question 7:
Find the intercepts cut off by the plane![]()
![]()
Dividing both sides of equation (1) by 5, we obtain

It is known that the equation of a plane in intercept form is
, where a, b, c are the intercepts cut off by the plane at x, y, and z axes respectively.
Therefore, for the given equation,
![]()
Thus, the intercepts cut off by the plane are
.
