\n" ); document.write( "The response from the other tutor shows a formal way of finding the answer.

\n" ); document.write( "On a less formal and more intuitive level, if the two lines are symmetric about the y-axis then their slopes are the same size but opposite signs, and the y-intercepts are the same.

\n" ); document.write( "The given line y = -x+2 has slope -1 and y-intercept 2, so the second line has slope 1 and y-intercept 2

\n" ); document.write( "ANSWER: y = x+2
