Question

graph each system. use the graph to find the solution and to determine the name of the system. system: y=2x+1 y=x-2. solution:____ name of the system:_______

Answer 1

Given:

$\begin{gathered} y=2x+1\ldots\ldots\ldots(1) \\ y=x-2\ldots\ldots\ldots(2) \end{gathered}$

To find the solutions:

Let us find three points to plot the graph.

From equation (1),

From equation (2),

Then, the graph is,

Hence, the solution is (-3, -5).
