What is the equation you are solving?
Using translation concepts, we have that:
- For the translation, she has to communicate if it is up, down, left or right and the number of units.
- For a reflection she must communicate over which line the reflection happened.
<h3>What is a translation?</h3>
A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.
A translation is either shift left/right or bottom/up, hence she has to communicate if it is up, down, left or right and the number of units.
A reflection is over a line, hence she must communicate over which line the reflection happened.

Answer:

Step-by-step explanation:
Recall that the formula for density is:

therefore for this case we have:

I would say that the correct answer is D. because y is always the numerator while x is the denominator for the equation y2 - y1/x2 - x1 which means if there is two y's or two x's on the same line you subtract the second one from the first one. If there is only one y and/or x and the other is 0 on the same line, it stays at y or x without subtracting y2 - y1 or x2 - x1.
Since b is on the y coordinate and -a is on the x coordinate, you would make it b/a while -a is gonna be a positive since the lines are going up and to the right. Now, since c is the y coordinate and d is the x coordinate, make C the numerator and d the denominator since y is always the numerator and x is the denominator for these parallel line figures on the graph and the equation will be equaled to the fraction to the other fraction for parallel lines.
So, your answer would be D. b/a = c/d
Hope this helps, and is correct!
