On a coordinate plane, how are the locations of the points (-4 , 8) and (-4 , -8) related?
1 answer:
Answer:
A. reflection across the y-axiss
Step-by-step explanation:
Given:
The locations of the two points are (-4 , 8) and (-4 , -8).
To find:
The relation between two points.
From the given points (-4, 8) and (-4 , -8), it is clear that the y-coordinates are same but the sign of x-coordinates are opposite.
If a figure is reflected across the y-axis, then we change the sign of x-coordinate and the y-coordinates remain same, i.e.,
→
For (-4,8)
→
So, it is reflection across the y-axis.
Therefore, the correct option is A.

Answer:
B is the Answer.
Step-by-step explanation:
A transformation of a function can be represented by
where a is the vertical stretch or compression, b is the horizontal stretch or compression. H is the shift horizontally and k is the shift vertically.
The new function has a 2 instead of 1 on the orginally function. The function will stretch since 2 is greater than 1.
B is the answer.
