  • (-m,3) is a solution .
  • Put in equation


\\ \qquad\quad\sf\longmapsto 4x+9y-3=0


\\ \qquad\quad\sf\longmapsto 4(-m)+9(3)-3=0


\\ \qquad\quad\sf\longmapsto -4m+27-3=0


\\ \qquad\quad\sf\longmapsto -4m+24=0


\\ \qquad\quad\sf\longmapsto -4m=-24


\\ \qquad\quad\sf\longmapsto m=(-24)/(-4)


\\ \qquad\quad\sf\longmapsto m=6
