(a) Write a approx equation of the line best fit. (b) What is the time spent on 12 hours? (pic below)

Question

The scatter plot shows the time spent watching TV ,X, and the time spent doing hw,Y, by each of 24 students last week.(a) Write an approx. equation of the line of best fit. (b) Using ur equation, What is the time spent on 12 hrs?

Answer 1

1. From the scatter plot, you would try to draw a line that best represents the trend in the data points. This line is called the line of best fit, or the regression line.
2. Once you have drawn the line, select two points on the line (not necessarily data points, just points that lie on the line you drew). Record their coordinates as (x1, y1) and (x2, y2).
3. Calculate the slope (m) of the line using the slope formula:
4. m = (y2 - y1) / (x2 - x1)
5. Identify the y-intercept (b) of the line, which is the point where the line intersects the y-axis.
6. Write the equation of the line in the slope-intercept form:
7. y = mx + b
8. To answer part (b), you would substitute X = 12 (time spent watching TV) into the equation and solve for Y (time spent doing homework):
9. Y = m(12) + b

Without the actual scatter plot or any data points, I'm unable to give you the specific equation or the result for 12 hours of TV time. If you can provide the data points or the slope and y-intercept of the line, I would be happy to help you further.
