    Answer:

    yes

    Step-by-step explanation:

    Here, x=2 and y=-1

    If these points lie on the line y= 3-2x,then they must satisfy the equation of the line (also mean they must be equal)

    So on solving the equations putting the value of x and y, we get

    y=3-2x

    or,-1=3-2*2

    or,-1=3-4

    Therefore, -1=-1
