Write an equation of the line containing a given point and perpendicular to the given line.
\n" ); document.write( "(6,7); 4x + y = 5
\n" ); document.write( ":
\n" ); document.write( "Find the slope of the given equation by putting it in the slope intercept form
\n" ); document.write( "4x + y = 5
\n" ); document.write( "y = -4x + 5
\n" ); document.write( "slope (m1) = -4
\n" ); document.write( ":
\n" ); document.write( "The relationship of the slopes of perpendicular lines is m1*m2 = -1
\n" ); document.write( "We know m1, find m2
\n" ); document.write( "-4*m2 = -1
\n" ); document.write( "Divide both sides by -4
\n" ); document.write( "m2 = +\"1%2F4\", this is slope of the equation we are looking for
\n" ); document.write( ":
\n" ); document.write( "Use the point/slope form here: y - y1 = m(x-x1)
\n" ); document.write( "Given: x1=6, y1=7
\n" ); document.write( "y - 7 = \"1%2F4\"(x - 6)
\n" ); document.write( "y - 7 = \"1%2F4\"x - \"6%2F4\"
\n" ); document.write( "y = \"1%2F4\"x - \"6%2F4\" + 7
\n" ); document.write( "y = \"1%2F4\"x - \"6%2F4\" + \"28%2F4\"
\n" ); document.write( "y = \"1%2F4\"x + \"22%2F4\"
\n" ); document.write( "let's just call it
\n" ); document.write( "y = \"1%2F4\"x + 5.5; is the equation (green) and passes thru 6.7
\n" ); document.write( ":
\n" ); document.write( ":
