1. The problem statement, all variables and given/known data Find the distance from the point A = (1; 0; 2) to the plane passing through the point (1; 2; 1) and perpendicular to the line given by the parametric equations x = 7, y = 1 + 2t, z = t - 3. 2. Relevant equations d = | (PS dot n)/|n|| 3. The attempt at a solution Set n = <0, 2, 1> from the line given |n|= sqrt(5) I am confused about finding the S point. Would the second point be the one that passes through the plane? If so, PS = <0, -2, -1> so PS dot n = <0, -4, -1> and it would become something like -4/sqrt(5) + -1/sqrt(5). I get -5sqrt(5)/5 which becomes |-sqrt(5)|. In general, when do we use intercepts (recommended by the textbook) and how vs just the point on the plane?
