Answer:
Use the substitution method to solve the equations:
Since y = x + 3 and y = 3x + 1, we know that x + 3 = 3x + 1
Set those values equal to each other:
3x + 1 = x + 3
Solve:
2x + 1 = 3
2x = 2
x = 1
Plug the x back into either one of the given equations to get y:
y = 1 + 3 = 4
y = 3(1) + 1 = 4
So your coordinate will be (1,4)
