The rule for clockwise rotation of 90 degrees about the origin is (-y, x).
So (-1,9) would now be (-9,1).
Hope this Helps!!
Answer:
yes they form a proportion
<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>
Answer:
2) C
3) D
4) D(5,-5) E(2,-7) F(4,-1) G(8,-8)
Step-by-step explanation:
P(x) to P(x+2), you need to graph the same but shift 2 units to the left.
New function :
Max = 4 ,coordinate points (-5, 0) and (5,0)
