can you please help me find, the equation of the line: passing through (6,6) and perpendicular to 5x-3y-8=0
\n" ); document.write( ":
\n" ); document.write( "Put the equation in the slope/intercept form to find the slope
\n" ); document.write( "5x - 3y - 8 = 0
\n" ); document.write( "-3y = -5x + 8
\n" ); document.write( "y has to be positive, multiply both sides by -1
\n" ); document.write( "3y = 5x - 8
\n" ); document.write( "divide both sides by 3
\n" ); document.write( "y = \"5%2F3\"x - \"8%2F3\"
\n" ); document.write( ":
\n" ); document.write( "slope m1 = \"5%2F3\"
\n" ); document.write( "the relationship of perpendicular lines: is m1*m2 = -1, to find m2
\n" ); document.write( "\"5%2F3\"*m2 = -1
\n" ); document.write( "multiply both sides by 3/5
\n" ); document.write( "m2 = \"-3%2F5\" is the slope of the perpendicular line
\n" ); document.write( ":
\n" ); document.write( "Use the point/slope form to find the equation of the perpendicular line
\n" ); document.write( "y - y1 = m(x - x1)
\n" ); document.write( "x1 = 6, y1 = 6, m=-3/5
\n" ); document.write( ":
\n" ); document.write( "y - 6 = \"-3%2F5\"(x - 6)
\n" ); document.write( "y - 6 = \"-3%2F5\"x - \"-18%2F5\"
\n" ); document.write( "y - 6 = \"-3%2F5\"x + 3.6
\n" ); document.write( "y = \"-3%2F5\"x + 3.6 + 6
\n" ); document.write( "y = \"-3%2F5\"x + 9.6; the equation of the perpendicular line
\n" ); document.write( ":
\n" ); document.write( "Check this, substitute 6 for x in the equation and ensure that y = 6
\n" ); document.write( "
