Question

Solve the following system of equations by graphing. Graph the system below andenter the solution set as an ordered pair in the form (x, y). If there are no solutions,enter None and enter ALL if there are infinite solutions.2 - y = 12 +y = -7Pls see the picture

Answer 1

Given:

The system of equations is given as,

`\begin{gathered} x-y=1 \\ x+y=-7 \end{gathered}`

The objective is to find the solutions to the equations.

Step-by-step explanation:

The graph of the equation x-y = 1 will be,

Similarly, the combined graph of x-y = 1 and x+y = -7 will be,

By observing the above graph the point of intersection is,

`(x,y)=(-3,-4)`

Hence, the solution of the graph is (-3,-4).
