Question

I’m desperate for help!!

Answer 1

When we reflect every point over the x axis...

• S(2, -4) becomes S ' (2, 4)
• T(9, -4) becomes T ' (9, 4)
• U(9, -1) becomes U ' (9, 1)
• V(2, -1) becomes V ' (2, 1)

The rule you use is $(x,y) \to (x,-y)$

The x coordinate stays the same while the y coordinate flips in sign (in this case from negative to positive)
