Find intercepts from an equation

If a graph is symmetric with respect to the x-axis and the point (-2, 3) is on the graph, then what point is also on the graph? If a graph is symmetric with respect to the y-axis and the point (-2, 3) is on the graph, then what point is also on the graph? If a graph is symmetric with respect to the origin and the point (-2, 3) is on the graph, then what point is also on the graph? (-2, 3) (-2, -3) (2, 3) (2, -3)

x-Axis: y-Axis: Origin: Not equivalent so not symmetric with respect to the x-axis. IS equivalent so symmetric with respect to the y-axis. y-Axis: Not equivalent so not symmetric with respect to the origin. Origin:

origin symmetry
