*y*= (-4/5)

*x*" in your calculator. You can do the same with all the answer choices, and eyeball pretty easily which one is a true reflection across the

*x*-axis.

Let's assume for a minute that you're doing this question without a graphing calculator, though. A reflection across the

*x*-axis negates the

*y*-values of your graph. How will that affect the slope? Well, let's use the same equation I made up above to see:

2 easy points to find on that graph are (0,0), and (5,-4). If I reflect those two points across the

*x*-axis, what happens? (0,0) stays the same. (5,-4) reflects to (5,4), because we're negating the -4, to get +4. What's the slope of a line that goes through (0,0) and (5,4)?

**(B) is our answer.**
