    reflection in axis

    Okay, new question.

    Describe how the point (-3,5) would change if you reflected it across the x-axis and vertically stretched it by a scale factor of 3? I got (3,15) while my teacher got (3,-15)

    I honestly think I'm right on this one.

    If you reflected it across the x-axis it would become (-3,-5) then the vertical stretch would give?
