\"\"

\

The line equation in slope-intercept form is \"\",

\

where m is the slope and b is the y-intercept.

\

Write the two functions as co-ordinates

\

\"\" as \"\"

\

\"\" as \"\"\"\"

\

First find the slope

\

m = \"\"

\

    = \"\"                (Substitute \"\" and \"\")

\

      = \"\"                      (Product of two same signs is positive)­­

\

    = \"\"                            (Add: \"\")­­

\

    = \"\".                                     (Divide: \"\")­­ \"\"

\

The line crosses the y-axis at (0, 3). So the y-intercept is 3.

\

Substitute \"\"and \"\" in slope-intercept form line equation.

\

\"\"

\

\"\"                        (Simplify)

\

\"\"

\

The function is \"\".
