(1,2):y*2=4x

Question

use symmetry to find at least one more point on the graph

Answer 1

By symmetry, we know that if the point (x, y) is on the graph of the equation y = 2x, then the point (-x, -y) must also be on the graph.

Let's find another point using this symmetry property:

If we take x = 2, then y = 4 (from the equation y = 2x).

Therefore, the point (2, 4) is on the graph.

Using symmetry, the point (-2, -4) must also be on the graph.

Therefore, we have at least one more point on the graph: (-2, -4).
