how can i write the equation of a line that passes throught (-2,-1) and is perpendicular to x-2y=6?
\n" ); document.write( "-----
\n" ); document.write( "Find slope of the given line:
\n" ); document.write( "2y = x-6
\n" ); document.write( "y = (1/2)x - 3
\n" ); document.write( "----
\n" ); document.write( "Slope = 1/2
\n" ); document.write( "-------
\n" ); document.write( "Slope of perpendicular line must be -2
\n" ); document.write( "-----
\n" ); document.write( "Form: y = mx + b
\n" ); document.write( "Solve for \"b\":
\n" ); document.write( "-1 = -2*-2+b
\n" ); document.write( "b = -5
\n" ); document.write( "-----
\n" ); document.write( "Equation:
\n" ); document.write( "y = -2x-5
