Plot the graph of the equations:
\n" ); document.write( "10x - 4y = 3
\n" ); document.write( "If x = 0, y = -3/4
\n" ); document.write( "If y = 0, x = 3/10
\n" ); document.write( "---------------------
\n" ); document.write( "Plot the points: (0,-3/4) and (3/10,0)
\n" ); document.write( "Draw a line thru them to get:
\n" ); document.write( "\"graph%28400%2C300%2C-10%2C10%2C-10%2C10%2C%285%2F2%29x-%283%2F4%29%29\"
\n" ); document.write( "===============================\r
\n" ); document.write( "\n" ); document.write( "and 5x - 2y = 6 and interpret the result
\n" ); document.write( "Solve for \"y\":
\n" ); document.write( "y = (5/2)x-3
\n" ); document.write( "If x = 0, y=-3
\n" ); document.write( "If x = 2, y = 2
\n" ); document.write( "---------------------
\n" ); document.write( "Plot the points: (0,-3) and (2,2)
\n" ); document.write( "\"graph%28400%2C300%2C-10%2C10%2C-10%2C10%2C%285%2F2%29x-3%29\"
\n" ); document.write( "======================================
\n" ); document.write( "Find the point of intersection. The x/y values
\n" ); document.write( "of that point satisfy both equations.
\n" ); document.write( "=======================================
