I think it is D. You can see that the triangle has flipped over the Y axis and the one point moved 2 places.
Answer: 1 solution
An augmented matrix for the system is
[2,6,12;1,1,2] where we will call the first two columns A and the third b. A is linearly independent since it is row equivalent to the identity matrix, which tells us that for any b there will be a unique solution (x,y).
Steps:
y2-y1/x2-x1
(7-3)/(5-3)= 4/2=2
[2 is the slope]
Now to find the the y-intercept
-take a random point I chose (3,3)
3=2(3)+c
3=6+c
3-6=c
-3=c
y-intercept is -3
Substitute and the answer is:
y=2x-3
Hope this helps and mark me the brainiest!!
