Area decreases by

Answer:
0.5
Step-by-step explanation:
22.7: 45.4 = 22.7/45.4
= 227/454
= 0.5
Looking at the data it looks like a line. So the answer will be in y+mx+b format.
Knowing it is a line eliminates answers b and c.
looking at options a is says it starts at about .1 when x is zero. We can see this looks pretty close as the left-most dot is below 1 already.
The slope on a is 1/2--> increasing 1 vertically for every 2 horizontally. The pattern mostly follows that rule.
Therefore a (y=1/2x+.1) would be the correct answer
