\

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

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

x

\ 		     0    2      4
\

y

\ 		     12    6      0
\

The difference of the x values is 2, and the difference of the y values is \"\"6, then \"\".

\

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

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

x

\ 		     0      2      4
  –3x     0    –6   –12
\

y

\ 		     12      6      0
\

The difference in y values is 12 of the difference of \"\" values.

\

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

\

The solution of the equation is \"\".
