Scatter Plot Review

The scatter plot shows the number of moves, x, and the number of hours, y, it takes to complete each game in a chess tournament. Which statement is a correct interpretation of the slope of the linear model?

• The average moves per game is 20.

• The average game is 1/20 of an hour.

• The average game has 20 moves per hour.

• After 1 hour, 1/20 of the total moves have been made.

Deon collects data on the prices of one-bedroom apartments and their distances from the town center. He creates the scatter plot from the data as shown. Which statement is true based on the scatter plot?

• There are multiple outliers in the scatter plot.

• There is a positive association between distance to town center and price.

• There is a nonlinear association between distance to town center and price.

• As the distance an apartment is from the town center increases, the price decreases.

Which statement is the MOST APPROPRIATE description of a line of best fit?

• The line of best fit should always have a y-intercept of 0.

• The line of best fit should intersect most, if not all, of the points in the scatter plot.

• The line of best fit should intersect the leftmost and rightmost points in the scatter plot.

• The line of best fit should have roughly an equal number of points in the scatter plot below and above it.
