    sry.....

  • MATH PLS HELP CHECK ANSWERS -

    For number 3 and 6, you can simply test solutions by substituting each of the x and y coordinates for x and y in the equation.

  • MATH PLS HELP CHECK ANSWERS -

    #3 since y increases by 3 when x increases by 1, the slope is 3/1 = 3.
    Only one choice has a slope of 3.

    And, as Leo said, you can just plug in the x's and see whether the y's match!

    #4 ok
    #5 ok
    #6 looks like A to me. Did you even try the given points?
    #7 ok
    #8 ok

    You did ok, for the ones where you provided an answer.
