Question

Solve this system of equations by graphing. First graph the equations, and then type the solution.y=x+4x=–5

Answer 1

We have the two equations

`\begin{gathered} y=x+4 \\ x=-5 \end{gathered}`

To solve the systems of equation by graphing, we will plot the two lines on the same graph and then find the point of intersection

The solution is the graph below

From the graph given, the point of intersection is the solution, and it is found to be

`\begin{gathered} (-5,-1) \\ x=-5 \\ y=-1 \end{gathered}`
