Observe the figure, then make a table of ordered pairs.

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

\ x \	–2	0	2	4
\ y \	9	6	3	0

The difference of the x values is 2, and the difference of the y values is $\"\"$ 3, then $\"\"$ .

Make a table of x, y coordinates and $\"\"$ ordered pairs.

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

The difference in x values y values are 6.

The difference in y values is six of the difference of $\"\"$ values.

Then the equation of the function $\"\"$ . $\"\"$

The solution of the equation is $\"\"$ .
