write an equation in standard form of the line that passes through the two points:\r
\n" ); document.write( "\n" ); document.write( "(9,-2), (-3,2)
\n" ); document.write( "------------------------------------------\r
\n" ); document.write( "\n" ); document.write( "Do it like this one:
\n" ); document.write( "=========================
\n" ); document.write( " write an equation in standard form of the line that passes through the two points:\r
\n" ); document.write( "\n" ); document.write( "(-3, -3),(7,2)
\n" ); document.write( "-------------
\n" ); document.write( "Find the slope, m
\n" ); document.write( "m = diffy/diffx = (-3-2)/(-3-7) = -5/-10
\n" ); document.write( "m = 1/2
\n" ); document.write( "----------
\n" ); document.write( "Use y = mx + b and either point to find b
\n" ); document.write( "2 = (1/2)*7 + b
\n" ); document.write( "b = -3/2
\n" ); document.write( "---------
\n" ); document.write( "eqn is y = mx + b
\n" ); document.write( "y = (1/2)x - 3/2 (slope-intercept form)
\n" ); document.write( "------
\n" ); document.write( "x - 2y = 3 (standard form)
\n" ); document.write( " \n" ); document.write( "
\n" );
