Question

Vector u has its initial Point at (15,22) and it’s terminal point at (5,-4)

Answer 1

so let's firstly find the component form of "u", keeping in mind that "v" is really in the opposite direction and twice as long, so v = -2u.

`\bf \stackrel{u}{(15,22),(5,-4)}\implies \stackrel{\textit{\underline{u} component form}}{<~5-15~~,~~-4-22~>}\implies \stackrel{u}{<-10~,~-26>} \\\\\\ v=-2u\implies v=-2<-10~,~-26>\implies v=<20,52>`
