Answer:

a) J':(-7,7) K':(-5,2) L':(-2,3)

b) The x coordinates remained the same, the y coordinates swapped from negative to positive.

Step-by-step explanation:

Aside: I'm using J', K', and L' to denote the new locations of J,K,L after the reflection.

When an object is reflected over the x-axis, it means it's positive points will flip to negative y space, and negative points will flip to positive y space.

That said, J, for instance, will have the same X-coordinate, but its Y-coordinate will flip from negative to positive. Doing this with every vertex mirrors the triangle over the X-axis.

Therefore, J:(-7,-7) will become J':(-7,7), and likewise with K and L becoming K':(-5,2) and L':(-2,3).
