Answer:
Option 3, x=t, y=5t-3
Step-by-step explanation: Plug in the t value for x, and if that gets the corresponding y value then that's the answer.
We have an equation y=5x-3.
If we let x=-3t, then 5(-3t)-3=y so y= -15t-3, so fourth option wrong
If we let x=t, then y=(5t)-3 and y does indeed 5t-3 , third option is right.
