How do you determine the equation of a line that has the same y int.
\n" ); document.write( " as the line y=8x+6?
\n" ); document.write( "Any equation in the form y = mx+6 has a y intercept of 6
\n" ); document.write( ":
\n" ); document.write( "and is perpendicular to the line 4x+7y-3=0
\n" ); document.write( "Put the equation into slope intercept form to find the slope
\n" ); document.write( "4x + 7y - 3 = 0
\n" ); document.write( "7y = -4x + 3
\n" ); document.write( "y = \"-4%2F7\"x + \"3%2F7\"
\n" ); document.write( ":
\n" ); document.write( "Slope relationship between perpendicular lines, m1*m2 = -1
\n" ); document.write( "m1 = \"-4%2F7\" find m2
\n" ); document.write( "\"-4%2F7\" * m2 = -1
\n" ); document.write( " multiply both sides by \"-7%2F4\"
\n" ); document.write( "m2 = \"7%2F4\"
\n" ); document.write( ":
\n" ); document.write( "The equation of the perpendicular line with a y intercept of 6:
\n" ); document.write( "y = \"7%2F4\"x + 6
\n" ); document.write( "
\n" );
