Answer: (0, -5) and (1, -2)

Infinitely many others are possible.

=================================================

Step-by-step explanation:

Replace x with 0 and simplify to get...

y = 3x-5

y = 3(0)-5

y = 0-5

y = -5

When x = 0, it leads to y = -5

One ordered pair is (x,y) = (0, -5)

Let's repeat those steps for x = 1

y = 3x-5

y = 3(1)-5

y = 3-5

y = -2

Another ordered pair is (1, -2)

As you can see, we can pick anything we want for x to get some paired y output. There are infinitely many x values to pick from. This means there are infinitely many ordered pairs for (x,y).

When it comes to graphing, you only need two points at minimum to form a straight line.
