Chapter 8.10, Problem 8PPS

To determine

The solution of system equations $\begin{array}{l}y=2x\\ y=x+1\end{array}$ is to be calculated by using the graphing method.

Answer to Problem 8PPS

The graphing solution for system of equation $\begin{array}{l}y=2x\\ y=x+1\end{array}$ is $\left(1,2\right)$

  

Explanation of Solution

Given:

Two equations are as:

  $\begin{array}{l}y=2x\\ y=x+1\end{array}$

The equations are:

  $y=2x$....... (1)

  $y=x+1$....... (2)

Now, draw graph of both equations as:

  

Form graph:

The point of the intersection of the system of two equations is $\left(1,2\right)$ which nothing but the solution of the graphing equations is.

Conclusion:

So, the solution of the system of eqns. is $\left(1,2\right)$
