Answer:
- see attached for a graph
- solution: (x, y) = (-1, 3)
Step-by-step explanation:
The first line has a slope of -3 and a y-intercept of 0. It will go through the origin and the point (-1, 3).
The second line has a slope of 1 and a y-intercept of 4. It will go through the points (0, 4) and (-4, 0).
The solution to the system of equations is the point where the lines cross, (-1, 3).
