The equation 'y=3-2x' is an equation of a line.

For the ordered pair of numbers we have:

The first number in an ordered pair tells how far across left or right to go on the X line.

The second number in an ordered pair tells how far up or down to go on the Y line.

Plug 'x = 0' into 'y=3-2x' to find the first pair:

y = 3 - 2*0

y = 3

The first pair is (0, 3).

Plug 'x = 1' into 'y=3-2x' to find the first pair:

y = 3 - 2*1

y = 1

The second pair is (1, 1).
