You can make one equation equal to t instead of y or x. I decided to make the equation y = t - 4 equal to t
y + 4 = t + (-4 + 4)
t = y + 4
Now in the other equation ( x = 3t + 1) you can replace t with y + 4 and solve for y
x = 3(y + 4) +1
x = 3y + 12 + 1
x = 3y + 13
x - 13 = 3y
y = x/3 -13/3
^^^I assume that's what you meant in the fourth opption when you wrote "y = x - 13/3"
Hope this helped!

Answer:
The correct option is C) [tex]y=\frac{x-13}{3}[/tex].
Step-by-step explanation:
Consider the provided parametric equations.
[tex]x=3t+1......(1)[/tex]
[tex]y=t-4......(2)[/tex]
The equation (2) can be written as:
[tex]y+4=t[/tex]
Substitute the value of t in equation (1).
[tex]x=3(y+4)+1[/tex]
[tex]x=3y+12+1[/tex]
[tex]x=3y+13[/tex]
[tex]x-13=3y[/tex]
[tex]y=\frac{x-13}{3}[/tex]
Therefore, the correct option is C) [tex]y=\frac{x-13}{3}[/tex].
