Answer

(a) The point $(6,2)$ does not lie on the graph. (b) The point $(-2,3)$ does not lie on the graph.

Work Step by Step

(a) We can verify if the point $(6,2)$ satisfies the equation of the graph: $3x-2y = 3(6)-2(2) = 18-4 = 14$ The point $(6,2)$ does not lie on the graph. (b) We can verify if the point $(-2,3)$ satisfies the equation of the graph: $3x-2y = 3(-2)-2(3) = -6-6 = -12$ The point $(-2,3)$ does not lie on the graph.
