Yes because 1.2 is the same as 1.20 it's just that you removed the 0
<em>The coordinates for each point would be:</em>
M': (2,-2)
N': (4, 2)
O': (8, -1)
If the rule is (x, y) = (x + 2, y - 6), this is how you solve this problem...
M to M': (0 + 2, 4 - 6), then (2, -2)
N to N': (2 + 2, 8 - 6), then (4, 2)
O to O': (6 = 2, 5 - 6), then (8, -1)
Subtract the right side and you have
x² -10x -6 -2x -1 = 0
x² -12x -7 = 0
This corresponds to the selection ...
C. x² -12x - 7 = 0
