Since an arithmetic sequence is a sequence of numbers and the difference of any two successive members of the sequence is a constant
So this question is arithmetic because it keep minus by 7
from 19 - 7 = 12
12 - 7 = 5
5 - 7 = -2
so common difference is -7
or you can check with arithmetic formular as
= 
+ (n−1)d
I will just put in the 4th term which is -2 and n will equal to 4
and is the 1st term which is 19
-2 = 19 + (4−1)d
-2 - 19 = 3d
d = 
d = -7
Answer:
C. G' (4,-7), R' (2,-3), T'(6,-4)
Step-by-step explanation:
Get a piece of paper and draw 2 intersecting lines, like how a graph looks like. Then get another paper that's transparent enough, and place a dot roughly where R would be. Rotate it 270* clockwise (3 times around 90 degrees), and R would be in the bottom right area. That means the figure would be around that area and you can base the coordinates from that.

Answer:
y = -x+3
Step-by-step explanation:
First find the slope
m = ( y2-y1)/(x2-x1)
= ( 2 - -3)/( 1 - 6)
( 2+3)/( 1-6)
5/ -5
-1
The slope is -1
We can use slope intercept form
y = mx+b where m is the slope and b is the y intercept
y = -x+b
Substitute a point into the equation
2 = -1 +b
Add 1 to each side
2+1 = -1+1+b
3 = b
y = -x+3
