ordered pairs: find 5 ordered pairs for the equation: y=3x-1

What is the value of y when x = 0?

y = 3 * 0 - 1 → y = -1

So the one of the ordered par could be (0, -1)

Now continue...

Please share your work with us ...even if you know it is wrong

If you are stuck at the beginning tell us and we'll start with the definitions.

What have you tried? Where are you stuck? For instance, you picked a random value for x, plugged it into the equation, simplified to find the corresponding value of y, wrote down that ordered pair, and... then what?

It might help if you understood that all your pairs look like $$\displaystyle (x,y)=(x,3x-1)$$.
Now pick five values for $$\displaystyle x$$ and simply use them in $$\displaystyle (x,3x-1)$$.

this is fairly simple really, first you have to determine the domain of the function. Seeing that there are no restrictions then the domain of this particular function is ALL REAL NUMBERS. So all you have to do is substitute any real number for x, which will be the x-ordinate. after simplifying the equation, solve for y, the solution for y will be the y-ordinate. now that you have the x-ordinate and y-ordinate, you have an ordered pair (x,y).
