Chapter 1.2, Problem 79AYU

To determine

To find: The point which is symmetric with respect to the origin to the point $\left(1,2\right)$ on the graph.

Answer to Problem 79AYU

$\left(-1,-2\right)$

Explanation of Solution

Given:

The point $\left(1,2\right)$ on the graph that is symmetric with respect to the origin.

Calculation:

If the point $\left(x, y\right)$ is on the graph which is symmetric with respect to the origin, then the point $\left(-x,-y\right)$ is also on the graph.

If the point $\left(1,2\right)$ is on the graph which is symmetric with respect to the origin, then the point $\left(-1,-2\right)$ is also on the graph.
