Which set of points represents a reflection of the triangle in the x-axis?

B

Step-by-step explanation:

The triangle is in the third quadrant and after it's reflection over the x  axis it will end up in the second quadrant. Which it's x coordinate is  negative and its y coordinate is positive.

The first ordered pairs are not in the solution because the triangle doesn't end up in the first quadrant.

The second  seems to be the solution because its x coordinates are all negative and its y coordinate are all positive.

(7,-2)  → (-7,2)

(-2,-2) → (-2,2)

(6,-7) →  ( -6,7)

the solution is h=10 because you add 9 to each side of the equation.

only 10/60 isn't equivalent

hope this : )
