Answer:
y = 0.10
Explanation:
Using the equation, y = -0.44x + 886.7:
You can plug in the year (2015) as the value of x into the given equation. In doing so, you'll be able to determine what the value of y is (the amount of sea ice left).
y = -0.44x + 886.7
y = -0.44(2015) + 886.7
y = -886.6 + 886.7
y = 0.10
Therefore, the amount of sea ice left in 2015 is 0.10.
Note: I'm not sure which unit of measure to follow because on the graph, it states that the "Area of Sea Ice" is (in millions of sq km); while in your given instructions, it states that "The scatterplot below shows the relationship between millions of square miles of arctic sea ice and the year." I don't know if the unit of measure matters, but no matter what, the y-value should be 0.10.
