Answer: 16/77
Step-by-step explanation: Here we're asked to evaluate ab
given that <em>a = 4/7</em> and <em>b = 4/11</em>.
So we start by plugging in our given
values for <em>a</em> and <em>b</em> into the problem.
If we do this, ab would then be (4/7)(4/11).
When multiplying two fractions together, we multiply across
the numerator and we also multiply across the denominators.
So (4/7)(4/11) is 16/77 which is our final answer.

How to calculate the coordinate of point by reflection</h3>
A point if reflected across the line 
by means of the following formula:
![P'(x,y) = P(x,y)+2\cdot [(x_{P}, -2)-P(x,y)]](https://tex.z-dn.net/?f=P%27%28x%2Cy%29%20%3D%20P%28x%2Cy%29%2B2%5Ccdot%20%5B%28x_%7BP%7D%2C%20-2%29-P%28x%2Cy%29%5D)
(1)
Where:
- Original point
- x-Coordinate of point P
- Resulting point
If we know that 
and 
, then the coordinates of the vertex is:
![P'(x,y) = (-2, 4) + 2\cdot [(-2,-2)-(-2,4)]](https://tex.z-dn.net/?f=P%27%28x%2Cy%29%20%3D%20%28-2%2C%204%29%20%2B%202%5Ccdot%20%5B%28-2%2C-2%29-%28-2%2C4%29%5D)
The coordinates of vertex B' is .
