Hi there, \n" ); document.write( "a) Gradient of line between (3,-7) and (-2,5) \n" ); document.write( "Gradient = y(2) - y(1)/x(2) - x(1) \n" ); document.write( "Gradient = 5 - (-7)/-2 - 3 \n" ); document.write( "Gradient = 12/-5 \n" ); document.write( "b) Using (-2,5) \n" ); document.write( "Y - Y₁= M ( X - X₁) \n" ); document.write( "Y - 5 = -12/5(X -(-2)) \n" ); document.write( "Y - 5 = -12/5(X + 4) \n" ); document.write( "c) Y = -12/5xX - 48/5 + 25/5 (5 = 25/5) \n" ); document.write( "Y = -12/5X - 23/5 \n" ); document.write( "You can multiply thro by 5 if you want whole numbers \n" ); document.write( "5Y = -12X - 23 \n" ); document.write( "Hope this helps:-) \n" ); document.write( " |
