The first line is y=(4/5)x -(23/5)
\n" ); document.write( "The second line MUST have a slope of (-5/4)
\n" ); document.write( "point slope formula
\n" ); document.write( "y-7=(-5/4)(x+3)
\n" ); document.write( "y=(-5x/4)+3\r
\n" ); document.write( "\n" ); document.write( "graph below shows these two plus yours (in blue); green is the perpendicular line to the original.\r
