Answer:
A. y = -6x +12
Step-by-step explanation:
The y-intercept on the graph is at y=12. (This eliminates answer C.)
The slope is negative (down to the right), eliminating answer D.
Y changes from 6 to 0 as x changes from 1 to 2, so the slope is ...
... (0 -6)/(2 -1) = -6
This is matched by the x-coefficient in ...
... y = -6x +12
so that is the equation of the line in the graph.
