Solve the system of equations below by graphing both equations with a pencil and paper. What is the solution? y=-x-1 y=x+3

Answer:
C. (-2, 1)
Step-by-step explanation:
See the attached graph.
The slope of the first line is -1, and its y-intercept is -1.
The slope of the second line is +1 and its y-intercept is +3.
The solution is the point that is common to both lines, (-2, 1).
