Help with Reflections?

hero (hero):

Use graph paper to figure it out. First reflect the point over the line y = -5, then afterwards, reflect the point over the line x = 1.

OpenStudy (anonymous):

I have no idea why I have not bought graph paper.

OpenStudy (anonymous):

Can I not figure out the "equation" without graph paper?

hero (hero):

You could use a graphing calc to do it. Try a site called desmos.com. You can plot the points and the lines using it. See if you can figure it out.

OpenStudy (anonymous):

Will do right now.

hero (hero):

Here... I set up the problem for you: https://www.desmos.com/calculator/6yzjbgi6d9

hero (hero):

Let me know what you get after reflecting the point across both lines.

OpenStudy (anonymous):

(-1, -6) ?

hero (hero):

Here's a better graph of it. https://www.desmos.com/calculator/01masavh0l Remember, to post the point that results after reflecting across BOTH lines...

hero (hero):

By the way, you're reflecting across the blue line first, then the green line.

OpenStudy (anonymous):

I have to be doing this completely wrong. It doesn't reflect across the line. It lands on the line.

OpenStudy (anonymous):

At (1, -5)

OpenStudy (anonymous):

I have no idea what I'm doing..
