Given equation of plane is 2x + y - z = 5.
On dividing both sides by 5, we get
2x/5 + y/5 - z/5 = 1
on comparing above equation of plane with the intercept form of equation of plane.
x/a + y/b + z/c = 1
where, a = x-intercept, b = y-intercept and c = z-intercept.
we get, a = 5/2
i.e., intercept cut off on X-axis = 5/2.
