The point (2,3) is on the line given by which equation below?

For this case we substitute the point in each of the equations and verify if the equality is met:
Option 1:
[tex]y = x-1\\3 = 2-1\\3 = 1[/tex]
It is not true
Option 2:
[tex]y = -3x\\3 = -2 (2)\\3 = -4[/tex]
It is not true
Option 3:
[tex]y = x + 1\\3 = 2 + 1\\3 = 3[/tex]
Is fulfilled
Option 4:
[tex]y = 3x\\3 = 3 (2)\\y = 6[/tex]
Answer:
The point belongs to the equation of the third option.
