Best ResponseYou've already chosen the best response.0\[\vec{a}^{\,}\cdot\vec{b}^{\,}=0 \rightarrow \sum_{1}^{i}a_{i}b_{i} = 0\] This is what you need to use.

Best ResponseYou've already chosen the best response.0hey orthogonal means these vectors are at 90 degree angle

Best ResponseYou've already chosen the best response.0the slope for the vector given <2,1> Slope= 1/2 = and a perpendicular slope to that would be 2/1 =2 which is the "negative reciprocal" of 1/2 we can see the slopes of each vectors given see which of those simplify to 2 slope A)(1,2) slope = 2/1=2 B. (3,6) Slope=6/3=2/1=2 < C. (2,3) Slope= 3/2=3/2 D. (1,2) Slope=2/1 =2 < So you are right
