<em>Question:</em>
<em>Triangles PQR and RST are similar right triangles. Which proportion can be used to show that the slope of PR is equal to the slope of RT?</em>
Answer:

Step-by-step explanation:
See attachment for complete question
From the attachment, we have that:





First, we need to calculate the slope (m) of PQR
Here, we consider P and R

Where


becomes
--------- (1)
Next, we calculate the slope (m) of RST
Here, we consider R and T

Where


becomes
---------- (2)
Next, we equate (1) and (2)

<em>From the list of given options (see attachment), option A answers the question</em>
A is the answer. It has no repeating x points buy it repeats on the y coordinate, which is okay. The answer is A just to say it again.
