\"\"

\

Given that the line contains \"\" is perpendicular to \"\" ; \"\"

\

Find the slope of \"\".

\

Let \"\" be \"\" and \"\" be \"\".

\

\"\"            (Slope formula)

\

\"\"                   (Substitute \"\")

\

\"\"                     (Simplify)\"\"

\

The product of slopes of two perpendicular lines is \"\".

\

Since \"\".

\

So, the line perpendicular to \"\" have the slope 2.

\

Graph the line.

\

Start at \"\", move up 2 units and then right 1 unit.

\

Label the point B. Draw \"\".
