document.write( "I am just unsure how to solve this problem.  I have converted problems from slope intercept form to standard, and standard to slope intercept, but there hasn't been an extra component (like the +7 in this one.)  I am also not sure how to do this when I only have one set of coordinates.  I tried figuring out the value of x and the value of y by (if x=0 then y=?, and if y = 0 then x=?) but I have two problems.  One is, the numbers I get (x= -7 and y= -7/2) don't make the problem true.  And even if they did, I don't know how to use them to help me make the original equation a line parallel to another point.  Help! </SPAN>\n" );
