other known points that must also lie on the graph

Question

okay the point on the graph is (-1,3) and the symmetric that is give is the x-axis . how do you find the other point that should be given on the graph

Answer 1

A graph is symmetric to the x axis when, if (a,b) is on the graph, then so is (a,-b).

Here, the point (-1, 3) is on the graph.

a = -1

b = 3

so, the point (-1, -3) must also be on the graph.
