If the points (1,1, ) and (-3,0,1) are equidistant from the plane 3 x+4 y-12 z+13=0 , then integer value of is

Options

Correct answer

B. 1

Step-by-step solution

Given A (1,1, ) and B (-3,0,1) are equidistant from 3 x +4 y -12 z +13=0 aligned & | 3(1)+4(1)-12 +13 9+16+144 | & | 20-12 13 |= | -8 13 | & 20-12 = 8 & 20-12 =8 or 20-12 =-8 =1 or = 7 3 aligned
