Answer :
Answer:
one solution: (1, 4)
Step-by-step explanation:
You want the graphs and number of solutions to the system of equations ...
- y = 3x +1
- y = 2x +2
Graph
The graph is attached. The first equation has a y-intercept of +1 and a slope of 3. The second equation has a y-intercept of +2 and a slope of 2.
The different slopes mean there is exactly one solution. The graph shows that solution to be (x, y) = (1, 4).

Additional comment
The slope is the x-coefficient when the equations are written in this "slope-intercept" form. It is the "rise/run" for the line on the graph. A slope of 3, for example, means the line has a rise of 3 grid squares for a run of 1 square (to the right). Knowing the y-intercept and slope makes it easy to graph the line.
