How or what is the technique of finding the correct approximate points in the section of Scatter Plotting? I basically know the formula after getting the plots and coming to a conclusion. My problem is that I don't choose the correct points on the graph.

How would I approach this problem?

The graph below shows the amount of money a store earns for selling T-shirts.     Part 1: Identify two ordered pairs, in the form (x,y), on the line of this proportional relationship  Part 2: Calculate the slope(m) using the points you identified (change in y-coordinates/change in x-coordinates)   Part 3: Interpret the slope in the context of the problem.  What does it tell you about how many t-shirts are sold and the amount of money earned?

The scatter plot shows the time spent watching TV, x, and the time spent doing homework, y, by each of 23 students last week. (a) Write an approximate equation of the line of best fit for the data. It doesn't have to be the exact line of best fit. (b) Using your equation from part (a), predict the time spent doing homework for a student who spends 15 hours watching TV. Note that you can use the graphing tools to help you approximate the line.

The scatter plot shows the number of years of experience, x, and the amount charged per hour, y, for each of 23 dog sitters in California. (a) Write an approximate equation of the line of best fit for the data. It doesn't have to be the exact line of best fit. (b) Using your equation from part (a), predict the amount charged per hour by a dog sitter with 10 years of experience. Note that you can use the graphing tools to help you approximate the line.
