You can put this solution on YOUR website!
1. Write an equation of the line containing the given point and parallel to the given line.
\n" ); document.write( "(5,7); x+7y=8
\n" ); document.write( "Find the slope of the line by solving for y
\n" ); document.write( "x+7y = 8
\n" ); document.write( "y = (-1/7)x + 8/7
\n" ); document.write( "Slope m = -1/7
\n" ); document.write( "-----------------
\n" ); document.write( "Use y = mx + b and the point to find b
\n" ); document.write( "7 = (-1/7)*5 + b
\n" ); document.write( "b = 54/7
\n" ); document.write( "y = (-1/7)x + 54/7
\n" ); document.write( "--------------------\r
\n" ); document.write( "\n" ); document.write( "2. Write an equation of the line containing the given point and parallel to the given line.
\n" ); document.write( "(-5,2); 4x=5y+7
\n" ); document.write( "Do it like #1
\n" ); document.write( "-------------------
\n" ); document.write( "3.Write an equation of the line containing the given point and perpendicular to the given line.
\n" ); document.write( "(4,8); 9x+y=8
\n" ); document.write( "Find the slope
\n" ); document.write( "y = -9x + 8
\n" ); document.write( "m = -9
\n" ); document.write( "The slope of lines perpendicular is the negative inverse, +1/9
\n" ); document.write( "Use y = mx + b and the point as in #1
\n" ); document.write( "----------------------------- \n" ); document.write( "

\n" );
