Question 1203210
<br>
The response from the other tutor shows a formal way of finding the answer.<br>
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.<br>
The given line y = -x+2 has slope -1 and y-intercept 2, so the second line has slope 1 and y-intercept 2<br>
ANSWER: y = x+2<br>
