Graph by Making a Table:

The equation is .

Make a table; choose some values for x and find the corresponding values for y.

\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \

\ x \	\ y = x – 2 \	\ y \	\ (x, y) \
\ – 2 \	\ = – 2 – 2 \	\    –4       \	\   (– 2, –4)     \
\ – 1 \	\ = – 1 – 2 \	\ – 3 \	\ (– 1, – 3) \
\ 0 \	\   = 0–2 \	\ –2 \	\ (0, –2) \
\ 1 \	\   = 1 – 2 \	\ –1 \	\ (1, –1) \
\ 2 \	\   = 2–2 \	\ 0 \	\ (2, 0) \

Use these ordered pairs to graph the equation.

1.     Draw a coordinate plane.

2.     Plot the points.

3.     Draw a line through these points.

4.Draw a line .
