Create a graph (bar graph, line graph, pie chart, or scatter plot) based on a given data set. Title the graph, label the axes, and choose a scale. Adjust the graph to fit the data, and then check your accuracy. The Gizmo can also be used to create a data table based on a given graph. 1. The scatter plot shows the annual profit for a certain airline (in millions of dollars) for years between 2000 and 2010. The equation of the trend line shown is y = 0.4x + 4.1, where x represents the year and y represents the profit. Use the equation to estimate the profit in 2002. Write an integer or a decimal. 2. Hart Interactive – Algebra 1 Lesson 15 M2 T ALGEBRA I S.146 . 2. Suppose that after fitting a line, a data set produces the residual plot shown below. An incomplete scatter plot of the original data set is shown below. The least squares line is shown, but the points in the scatter plot have been erased.
