work out and graph the following:
\n" ); document.write( "-contains the point (-3,-8) and is perpendicular to y = -3/4x + 6
\n" ); document.write( ":
\n" ); document.write( "Find the slope (m2) of the perpendicular line. The relationship between
\n" ); document.write( "perpendicular lines is m1*m2 = -1; m1 = -3/4, find m2
\n" ); document.write( "\"-3%2F4\"*m2 = -1
\n" ); document.write( "multiply both sides by -\"4%2F3\", results
\n" ); document.write( "m2 = +\"4%2F3\"
\n" ); document.write( ":
\n" ); document.write( "Find the perpendicular line using the point/slope form: y - y1 = m(x-x1)
\n" ); document.write( "where:
\n" ); document.write( "x1 = -3; y1 = -8, m = 4/3
\n" ); document.write( "y - (-8) = \"4%2F3\"(x - (-3))
\n" ); document.write( "y + 8 = \"4%2F3\"(x + 3)
\n" ); document.write( "y + 8 = \"4%2F3\"x + 4
\n" ); document.write( "y = \"4%2F3\"x + 4 - 8
\n" ); document.write( "y = \"4%2F3\"x - 4
\n" ); document.write( ":
\n" ); document.write( "Plot these two equations
\n" ); document.write( "y = x - 4
\n" ); document.write( "Table
\n" ); document.write( " x | y
\n" ); document.write( "-------
\n" ); document.write( " 0 |-4
\n" ); document.write( " 6 |+4
\n" ); document.write( " 9 |+8
