1) calculate the gradient of the line joining the following pairs of points :
\n" ); document.write( "(3,1) (5,4)
\n" ); document.write( "\"Gradient\" is slope.
\n" ); document.write( "Slope between any two points is:
\n" ); document.write( "(y2-y1)/(x2-x1)
\n" ); document.write( "(4-1)/(5-3)
\n" ); document.write( "3/2
\n" ); document.write( ".
\n" ); document.write( "2) calculate the gradient and y-intercept of the given straight lines.
\n" ); document.write( "3x-2y=8
\n" ); document.write( "put the given expression into \"slope-intercept\" form of a line:
\n" ); document.write( "y = mx + b
\n" ); document.write( ".
\n" ); document.write( "3x-2y=8
\n" ); document.write( "-2y=-3x+8
\n" ); document.write( "2y=3x-8
\n" ); document.write( "y=(3/2)x-4
\n" ); document.write( ".
\n" ); document.write( "slope is 3/2 (gradient)
\n" ); document.write( "y-intercept is -4\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
