Solve the system of equations below by graphing both equations with a
pencil and paper. what is the solution?
y=x+5
y=-2x-1

Graph using slope and the y intercept

So y=x+5
You would plot the y intercept (0,5) and then go up 1 and to the right 1

The next graph plot y intercept (0,-1) and then go down 2 and to the right 1

And should look like the image

And your solution should be (-2,3) which is option c
