write an equation for the line perpendicular to y = 3x - 5 that contains (-2,-3).
\n" ); document.write( "the relationship of the slopes of perpendicular lines m1 * m2 = -1
\n" ); document.write( "In this case m1 = 3, find the slope of the perpendicular line
\n" ); document.write( "3m = -1
\n" ); document.write( "m = \"-1%2F3\"
\n" ); document.write( ":
\n" ); document.write( "Using the point slope form y - y1 = m(x-x1),
\n" ); document.write( " x1=-2; y1=-3; m=\"-1%2F3\"
\n" ); document.write( "y -(-3) = \"-1%2F3\"(x -(-2))
\n" ); document.write( "minus a minus is a plus
\n" ); document.write( "y + 3 = \"-1%2F3\"(x + 2)
\n" ); document.write( "y + 3 = \"-1%2F3\"x - \"2%2F3\"
\n" ); document.write( "y = \"-1%2F3\"x - \"2%2F3\" - 3
\n" ); document.write( "y = \"-1%2F3\"x - \"2%2F3\" - \"9%2F3\"
\n" ); document.write( "y = \"-1%2F3\"x - \"11%2F3\" is the equation
\n" ); document.write( ":
\n" ); document.write( "looks like this
