Use scalar multiplication to determine the coordinates of the vertices of the dilated figure. Then, graph the pre-image and the image of the same coordinate grid. Quadrilateral WXYZ with vertex matrix [-1 5 5 -2] [2 5 3 -5] with a scale factor 3.

    I did that but when I plotted it, it looked nothing like the options?

    Oh so this is how a Jacobian works too,... sort of. Right @amistre64 ? Haha. That's what I initially thought this was.

    well, its not a jacobian (thats a cross product type thing) this is just scaling a vector really.

    the matrix is made of ordered pairs, and scaling each ordered pair by 3 results in a new scaled pair ...

    [-1 5 5 -2] [2 5 3 -5] [-1(3) 5(3) 5(3) -2(3)] [2(3) 5(3) 3(3) -5(3)] is NOT what youve worked.

    how do you read an ordered pair? (x,y)
