Question 1142071: Hello, I have no idea how to begin this question! Please help! (Sorry i don't know how to format matrices here)
A transformation is defined through the matrix equation +T%28X%2BB%29+=+X%27+ where,
T =| -1 0 |
.....| 0 -2|
B = |-1|
.......|5|
The equation of the image of the line L under this transformation is y=3x-5.
The equation of the line L is:
A. y=%283%2F2%29x-4%29
B. y=%28-3%2F2%29x%2B4
C. y=6x-6
D. y=-6x%2B6
