What is the solution to the system of equations graphed below?

The graphs cross at this point. Intersection points are solutions to systems of equations.

Put another way, (1,4) is on the blue line and on the red line simultaneously.

A point on the red line is a solution to the red equation. A point on the blue line is a solution to the blue equation.

Checking the

y = x+3

4 = 1+3 ... plug in x = 1 and y = 4 into the blue equation

4 = 4 solution works for the blue equation

y = 3x+1

4 = 3(1)+1 ... plug in x = 1 and y = 4 into the red equation

4 = 3+1

4 = 4 ... solution also works for the red equation

This fully confirms the solution

the answer will be the last one
