b)this system has indinetly many solutions
c)this system has no solution
d)(1,1) and (0,0)

    Isn't the second equation the same as the first?

    And how many points would satisfy the first?

    So what do you think?

    ohhhh so just one solution right?

  • algebra 1 - ,

    If you mean infinite not indinetly than the answer is C.
    2x-y-1=0 subtract 2x from each side
    -y-1 = -2x + 0 add 1 to each side
    -y = -2x + 1 multiply everything by -1
    y = 2x-1
    The equations are equal, so the system has infinite solutions.
