\"\"

\

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 \"\")

\

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

\

    = -5.                                 (Divide:\"\")­­

\

\"\"

\

The line crosses the y-axis at (0, -4). So the y-intercept is -4.

\

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

\

\"\"                         

\

\"\"                        (Simplify)

\

\"\"

\

The function is \"\".
