Reflection across y=x is a special case transformation
The original triangle has vertices A(-5,1), B(-4,3), C(-2,1), D(-3,-1) so the transformed triangle has vertices
A'(1,-5), B'(3,-4), C'(1,-2), D'(-1,-3)
Choice A'(1,-5)
Answer:
Step-by-step explanation:
This equation is in slope intercept form (
). This is called slope intercept form for a reason - 
is always the slope and 
is always the y-intercept.
We can see that the coefficient on the x-term is 
and the constant being added to it is 5.
This means 5 is the y-intercept.

Given the distance covered and the time elapsed, Ryashkina's average walking rate is approximately 3.97 meters per second.
<h3>What was Ryashkina's average walking rate?</h3>
Rate or speed is expressed as distance walked or traveled per unit time.
R = s/t
Given the data in the question;
- Distance covered s = 10,000m
- Time elapsed t = 41 minutes 56.23 seconds
- Rate r = ?
First convert 41 minutes to seconds.
⇒ 41min = ( 41 × 60 )s = 2460sec
Now, Elapsed time t = 2460s + 56.23s = 2516.23 second
Next, we determine the rate.
R = s / t
R = 10000m / 2516.23 s
R = 3.97m/s
Given the distance covered and the time elapsed, Ryashkina's average walking rate is approximately 3.97 meters per second.
