Answer:
see explanation
Step-by-step explanation:
Under a reflection in the x- axis
a point (x, y) → (x, - y), hence
A(- 6, 2) → A'(- 6, - 2)
B(- 9, 1) → B'(- 9, - 1)
C(1, - 6) → C'(1, 6)
If they have the same denominator, all you have to do is compare the numerators. The larger numerator makes it the larger ratio.
3.11111... = 3 + 1/9 = 28/9
Every time you see such a repeating decimal, it's basically a fraction with 9's in the denominator.
For example:
0.222... = 2/9
0.45454545... = 45/99
0.274274274... = 274/999
Y2-y1/ x2-x1 is the formula for slope
