ocr: The 1x2 vector A=[4 - 2] can be thought of as representing ans arrow in the coordinate plane. The arrow priginates at (0,0) and terminates at the point( (4,2). Multiplying the vector A=[4 - 2] by-2 not only stretches it 30 thatil it appearsionger, but also changes its direction. -2A=-214 2]=1-8-4] (-8,-4) - - - - - View scaling by: @3 - - 112 . - H - - Scaling a Vector
