"\\vec v\\cdot\\langle3, -1\\rangle=0"
"3v_1-v_2=0=>v_2=3v_1"
"|\\vec v|=1=>v_1^2+v_2^2=1"
"v_1^2+(3v_1)^2=1"
"v_1=\\pm\\dfrac{\\sqrt{10}}{10}"
"\\vec v=\\langle-\\dfrac{\\sqrt{10}}{10}, -\\dfrac{3\\sqrt{10}}{10}\\rangle" or
"\\vec v=\\langle\\dfrac{\\sqrt{10}}{10}, \\dfrac{3\\sqrt{10}}{10}\\rangle"
