Please answer this as soon as possible thank you I appreciate it

Answer:
a. Yes
Step-by-step explanation:
Plug the values into each expression to check
y - 3 = x
4 - 3 = 1
1 = 1
This checks out
2y = 2x + 6
2(4) = 2(1) + 6
8 = 2 + 6
8 = 8
This checks out so the coordinates do indeed satisify the equations
