Hi there, \n" ); document.write( "Sort out equation into y = mx + c form. \n" ); document.write( "4y+12x=12 \n" ); document.write( "4y = -12x + 12 \n" ); document.write( "y = -3x + 3 \n" ); document.write( "Gradient (Slope) = -3 \n" ); document.write( "Lines that are parallel to one \n" ); document.write( "another have equal gradients (Slopes) \n" ); document.write( "Using line equation: \n" ); document.write( "y - b = m(x - a) \n" ); document.write( "Where m = -3 \n" ); document.write( "(a,b) = (9,-10) \n" ); document.write( "y - (-10) = -3(x - 9) \n" ); document.write( "y + 10 = -3x + 27 \n" ); document.write( "y = -3x + 27 - 10 \n" ); document.write( "y = -3x + 17 \n" ); document.write( "Hope this helps :-) \n" ); document.write( " |
