Best ResponseYou've already chosen the best response.0Remember that to get vector equation you need any point that lies on to the line and a vector that goes in the same direction.

Best ResponseYou've already chosen the best response.2You could try\[\mathbf{r}(t)=\mathbf{P}+t(\mathbf{Q}\mathbf{P}),\qquad0\leq t\leq1.\]Notice that if \(t=0\), then \(\mathbf{r}(t)=\mathbf{P}\), and if \(t=1\), then \(\mathbf{r}(t)=\mathbf{Q}\).

Best ResponseYou've already chosen the best response.1first find the required parallel vector to the line PQ=<62,20,20)= <4,2,2>

Best ResponseYou've already chosen the best response.0so, i end up with r(t)=(2,0,0)+t(4,2,2). Is this correct?

Best ResponseYou've already chosen the best response.1r(t)=(2,0,0)+t(4,2,2 ) not 2 !!!
