Testing an equation for Symmetry

[@Sandra-jv7jt]

Omg thank you so much. I could never figure out why the equation was multiplied by -1 or +1 and you explained that so well!

Thanks so much! I'm in a math class meant for college students as a 10th grader, and had a bit of difficulty given I skipped this earlier. This video explained everything!

Thank you so much, but I just wanna know when do we have to multiply by −1?? because there are different equations that you don’t have to do it??

[@caroledelvecchio895]

Good question, Jake. I've found that the easiest way to see if two equations are equivalent is by writing them both as y =. Since we substitute -y for y to check for symmetry with respect to the x-axis or the origin, we need to multiply both sides by -1 whenever we have -y.
