Find the vectors direction of F= -2yi-xJ of the points below :- (-12-1), (-21-1),(3,0). (-1₁-2), (-3,-2), (-1,0)

Express the vector -9-7x- 15x² as a linear combination of p₁ = 2 + x +4x², p₂ = 1- x + 3x² and p3 3 + 2x + 5x²

Let / be the line through the point with coordinates (-2,1,0) in the direction of the vector 1 Which of the following points (given by their coordinates) lie on | 1? Select one: a. (-3, 1, -1) b. (-2, -1, 0) c. (-3, 2,-1) d. (-4, 3, 0)

A line contains the points P=(−6,−2,−3)P=(-6,-2,-3) and Q=(−4,−3,−6)Q=(-4,-3,-6). A vector equation of this line is →x=−−→OP+t−−→PQx→=OP→+tPQ→, where OO is the origin.If t=2t=2, what point does this give us from the equation?
