If j and k are nonzero integers, which pair of points must lie in the same quadrant? (j, j) and (k, k) (j, k) and (jk, jk) (j + k, 3) and (3, j + k) (3j, 3k) and (StartFraction 3 Over j EndFraction, StartFraction 3 Over k EndFraction) 3 1 –7 –6 –9 Yes, the values represent a function because each x-value is paired with only one y-value. Yes, the values represent a function because each y-value is paired with only one x-value. No, the values do not represent a function because the x-values are not in ascending order. No, the values do not represent a function because there is no single rule that relates each pair of values.
