Hi there, \n" ); document.write( "First find the gradient of the line \n" ); document.write( "between (2, -2) and (6,3) \n" ); document.write( "Gradient = y(2) - y(1)/x(2) - x(1) \n" ); document.write( "Gradient = 3 - (-2)/6 - 2 \n" ); document.write( "Gradient = 5/4 \n" ); document.write( "If two lines are parallel then they \n" ); document.write( "have the same gradient. \n" ); document.write( "Therefore the line containing the \n" ); document.write( "point (-4, 18) \n" ); document.write( "has the equation: \n" ); document.write( "y - 18 = 5/4 (x -(-4)) \n" ); document.write( "y - 18 = 5/4(x + 4) \n" ); document.write( "y - 18 = 5/4x + 5 \n" ); document.write( "y = 5/4x + 5 + 18 \n" ); document.write( "y = 5/4x + 23 \n" ); document.write( "OR \n" ); document.write( "4y = 5x + 92 (Multiplied thro' by 4) \n" ); document.write( "Hope this helps:-) \n" ); document.write( " |
