How to graph the line

y = 2 - x

Step 1: Make a T table with two points. The values 0 and 1 are usually convenient, although other choices are fine here. Notice that

For x = 0:

y = 2 - 0 = 2

For x = 1:

y = 2 - 1 = 1

We can now make the table below

This indicates the points

(0,2) and (1,1)

Step 2 Plot the two points on the xy-plane. Graph paper would be useful here.

Step 3

Connect the dots with a line using a ruler
