$\text{a) NOT a solution }\\\text{b) NOT a solution }\\\text{c) NOT a solution }\\\text{d) solution }$
$\bf{\text{Solution Outline:}}$ Substitute the given points in the given inequality, $x-5\gt0 .$ If the inequality is satisfied, then the given point is a solution. Otherwise, the given point is not a solution. $\bf{\text{Solution Details:}}$ a) Substituting the given point, $( 0,0 )$ in the given inequality results to \begin{array}{l}\require{cancel} x-5\gt0 \\\\ 0-5\gt0 \\\\ -5\gt0 \text{ (FALSE)} .\end{array} Hence, $( 0,0 )$ is NOT a solution. b) Substituting the given point, $( 5,0 )$ in the given inequality results to \begin{array}{l}\require{cancel} x-5\gt0 \\\\ 5-5\gt0 \\\\ 0\gt0 \text{ (FALSE)} .\end{array} Hence, $( 5,0 )$ is NOT a solution. c) Substituting the given point, $( -1,3 )$ in the given inequality results to \begin{array}{l}\require{cancel} x-5\gt0 \\\\ -1-5\gt0 \\\\ -6\gt0 \text{ (FALSE)} .\end{array} Hence, $( -1,3 )$ is NOT a solution. d) Substituting the given point, $( 6,2 )$ in the given inequality results to \begin{array}{l}\require{cancel} x-5\gt0 \\\\ 6-5\gt0 \\\\ 1\gt0 \text{ (TRUE)} .\end{array} Hence, $( 6,2 )$ is a solution. Hence, \begin{array}{l}\require{cancel} \text{a) NOT a solution }\\\text{b) NOT a solution }\\\text{c) NOT a solution }\\\text{d) solution } \end{array}
