Here is the problem:

\n" ); document.write( "\n" ); document.write( "What is the slope of the line x=-3t+10 and y=4t+2.
\n" ); document.write( "3t = -x+10
\n" ); document.write( "t = (-x+10)/3
\n" ); document.write( "-----
\n" ); document.write( "4t = y-2
\n" ); document.write( "t = (y-2)/4
\n" ); document.write( "----
\n" ); document.write( "Equate the \"t\" values:
\n" ); document.write( "(-x+10)/3 = (y-2)/4
\n" ); document.write( "Cross-multiply::::
\n" ); document.write( "3(y-2) = 4(-x+10)
\n" ); document.write( "3y-6 = -4x + 40
\n" ); document.write( "3y = -4x + 46
\n" ); document.write( "y = (-4/3)x + (46/3)
\n" ); document.write( "---------------------------\r
\n" ); document.write( "\n" ); document.write( "--------------------------
\n" ); document.write( "(a) m= -4/3
\n" ); document.write( "--------------------
\n" ); document.write( "(b) Where does the line cross the x-axis? (______,0)
\n" ); document.write( "y = (-4/3)x + (46/3)
\n" ); document.write( "(-4x+46)/3 = 0
\n" ); document.write( "-4x = -46
\n" ); document.write( "x = 46/4
\n" ); document.write( "-------------------\r
\n" ); document.write( "\n" ); document.write( "(c) Where does the line cross the y-axis? (0,______)\r
