Answer
The miller indices for the plane A is $(\bar 1,\bar1,1)$
The miller indices for the plane B is $(2,3,0)$
Work Step by Step
Plane A intersects the negative x-axis at 1, negative y axis at 1 and positive z axis at 1.
The intercept point for the plane A is $(-1,-1,1)$
The miller indices for plane A are $(\bar 1,\bar1,1)$
Plane B intercepts the x-axis at $\frac{1}{2}$, y axis at $\frac{1}{3}$ and parallel to z axis
The intercept point for the plane B is $(\frac{1}{2},\frac{1}{3},\infty)$
The miller indices for the plane B is $(2,3,0)$
