Question

The following scatter plot shows the billions of dollars spent by travelers in the United States since 1993.

Write an equation for the line of best fit and then predict how much money travelers will spend in 2008.

A.y=2x+380 travelers will spend about $410 billion in the year 2008.

B.y=2x+320 travelers will spend about $350 billion in the year 2008.

C.y=20x+320 travelers will spend about $620 billion in the year 2008.

D.y=20x+380 travelers will spend about $680 billion in the year 2008.

Answer 1

C

Explanation:

Answer 2

I think the correct answer from the choices listed above is option C. The line of best fit for the figure given above would be y=20x+320 so that travelers will spend about $620 billion in the year 2008.

From the plot, y-intercept is equal to 320 and the slope (400-350) / (4-1.5) = 20.
