Final answer:

To solve the system by graphing, plot the lines represented by the equations and find their point of intersection. The solution is x = 2 and y = 3.

Step-by-step explanation:

To solve the system of equations by graphing, we need to plot the lines represented by the equations and find their point of intersection.

Starting with the first equation:

  • 3x - y = -1

We can rewrite it as:

  • y = 3x + 1

Using the slope-intercept form, we know that the y-intercept is 1 and the slope is 3/1, which means for every 1 unit increase in x, there is a 3 unit increase in y.

Now, let's graph the second equation:

  • y = -x + 5

Using the slope-intercept form, the y-intercept is 5 and the slope is -1/1, which means for every 1 unit increase in x, there is a 1 unit decrease in y.

Plotting the lines on the graph, we find that they intersect at the point (2, 3).

Therefore, the solution to the system is x = 2 and y = 3.
