\n" ); document.write( "(a) The line passes through the points (0,7) and (3,0)
\n" ); document.write( "(b) The line given by the equation 3x-5y=15
\n" ); document.write( "(c) The line given by the equation y-4=3(x-9)
\n" ); document.write( "(d) The line that passes through the points (-2,-5) and (2,5)

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "(a)
\n" ); document.write( "The y-intercept is obviously given, y=mx+b, b=7.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "(b) and (c)
\n" ); document.write( "If you can start from Ax+By=C and solve for y in terms of x, then you can adjust into slope-intercept form and identify the y intercept.
\n" ); document.write( "\"By=-Ax%2BC\"
\n" ); document.write( "\"y=-%28A%2FB%29x%2BC%2FB\"
\n" ); document.write( "which is slope intercept form.
\n" ); document.write( "\"b=C%2FB\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "(e)
\n" ); document.write( "You are looking for the equation \"x%2B2y=2%2B2%2A3\" and if you understood (b) and (c) exercise items, then you can figure how what to do to finish.
