    Here, if the decimal value is \(= or < than~ 5, ~the ~decimal~value~changes~i.e,, \) 124.9=125. \(you~are~right~!!\) @itsnotjesse

    \(2x-3y-z=0\) \(2*(-2)-3*(3)-(-2)=0\)

    @itsnotjesse next one... the point has the form of \((x,y)\) so there are 4 points given, can you tell me what is the maximum value of the y given ? ?

    Correct, so we just need the y axis to be that long. so what interval of y you think we can take ?
