Answer: No, it's not a solution
========================================================
Step-by-step explanation:
The point (1,0) means x = 1 and y = 0 pair up together.
Replace each variable with those values to get
y = 3x
0 = 3(1)
0 = 3
We get a false statement, so that's why (1,0) is not a solution.
----------
If we plugged in x = 1, then we should get this y value
y = 3x
y = 3*1
y = 3
Meaning (1,3) is a solution. This point is on the line y = 3x.
