What is the question though in A #1
(-1,-2) would result in a relation that is no longer a function.
In the table, there's already x = -1 and y = -4. Function only gives a single y-value with x-value. If a single x-value gives two y-values then it'd not be Function.
If we add (-1,-2) in the table. The domain will be repetitive. Basically, we already have (-1,-4) and if we add (-1,-2) in the table, a single x-value will give TWO y-values which is not a function.
Answer:
the answer to the question is -1
Dilation is a transformation that preserves angles. This means that:
where O(3,-2) is a center of dilation.
These pairs of congruent angles are alternate angles formed with lines LM and L'M' and two transversals OL and OL'. Thus, lines LM and L'M' must be parallel. So option D is true.
If lines LM and L'M' are parallel, then their slopes are equal and option C is true.
Now, since a scale factor is 1/2, the image segment L'M' has length that is one-half of the length of segment LM. Therefore, option A is true and option B is false.
Answer: statement B is false.
