\n" );
document.write( "Here is the problem and I have the answer, although I'm not understanding how they got the answer: Do the following: (a) Write the equation in slope-intercept form. (b) Give the slope and y-intercept of the line. x=4y-7
\n" );
document.write( "(a) Y= 1/4x + 7/4 (How did they get this?)
\n" );
