    see the x coordinate of the vertical line in changes from x = 2 to x = 6

    it changes to x = 6 but the sharp point shifts left by 2

    shift the dotted figure to the right till the sharp point coincides with the original one

    you have to shift by 2. so that means the vertical like is at x = 8

    here are the options for the scale point: scale factor ; reduction scale factor 4; enlargement scale factor 3; enlargement scale factor ; reduction
