    Answer:

    Basically multiply the x and y coordinates of each point by 1/2

    For example, I’ll do C which is ( -2 , 10 )

    -2 * 1/2 = -1 and 1/2 * 10 = 5

    The new coordinate is ( -1 , 5 )

    Now you can try the other points

    Answer:

    Step-by-step explanation:

    mutiply x and y component by 4

    A(0 , 0) = (4*0 ,,4*0)

    A’ = (0 , 0)

    B(-2 , 8) = (-2*4 , 8*4)

    B’ = (-8 , 24)

    C(1 , 7) = (1*4 , 4*7)

    C’ = (4 , 28)
