Chapter 11: Q. 194 (page 1147)

In the following exercises, solve the system of equations by using graphing.
$\begin{array}{rcl} \{\begin{cases} x = - 2 \\ x^{2} + y^{2} = 4 \end{cases} \end{array}$

Short Answer

Expert verified

The solution is $(- 2, 0)$

Step by step solution

Step 1. Given information

The given system of equations is

$\begin{array}{rcl} \{\begin{cases} x = - 2 \\ x^{2} + y^{2} = 4 \end{cases} \end{array}$

Step 2. Graph the Equations.

Plot the graph of the equations on the same graph.

The blue line represents the first equation and the red line represents the second equation of the system.

Step 3. Determine the point of intersection

From the graph, it is observed that the point of intersection of both equations is $(- 2, 0)$ .
So, the solution of the system of equations is $(- 2, 0)$ .
