Hi there, \n" ); document.write( "y = -3x + 5 \n" ); document.write( "Lines that are parallel have \n" ); document.write( "the same gradient (slope) \n" ); document.write( "(m1 = m2) \n" ); document.write( "Using the gradient -3 \n" ); document.write( "from the line at the top. \n" ); document.write( "Using the line equation:- \n" ); document.write( "y - b = m(x - a) \n" ); document.write( "m = -3 \n" ); document.write( "(-2,-1) = (a,b) \n" ); document.write( "y -(-1) = -3(x - (-2)) \n" ); document.write( "y + 1 = -3(x + 2) \n" ); document.write( "y + 1 = -3x - 6 \n" ); document.write( "y = -3x - 6 - 1 \n" ); document.write( "y = -3x - 7. \n" ); document.write( "This is the equation. \n" ); document.write( "Hope this helps:-) \n" ); document.write( " |
