the line of best fit for a scatter plot is shown:

1. a scatter plot and line of best fit are shown. data points are located at 0 and 1, 2 and 1, 2 and 3, 4 and 3, 4 and 5, 6 and 3, 7 and 5, 9 and 4. a line of best fit passes through the y-axis at 1 and through the point 4 and 3.

what is the equation of this line of best fit in slope-intercept form?

y = 1x + one half

y = one half x + 1

y = 1x − one half

y = negative one half x + 1

2. a graph shows the survey results for a group of students who were asked how many honors classes they have taken and how many elective classes:

a scatter plot is shown with the title class choices. the x axis is labeled number of honors classes and the y axis is labeled number of electives. data points are located at 1 and 8, 3 and 6, 3 and 9, 5 and 3, 6 and 6, 6 and 9, 8 and 6. a line of best fit crosses the y axis at 9 and passes through the point 6 and 6.

how many elective classes would students likely have taken if they have taken 12 honors classes?

15, because y = one halfx + 9

12, because y = y = negative one halfx + 9

6, y = ˜one halfx + 9

3, because y = negative one halfx + 9
