HELPPPPPP DUE TONIGHTTT

The scatter plot shows the number of hours worked, x, and the amount of money spent on entertainment, y, by each of 23 students.
(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 money spent on entertainment for a student who works 10 hours.
Note that you can use the graphing tools to help you approximate the line.​

(a) The approximate equation of the line of best fit is y≈2x+10.

(b) Using this equation, the predicted money spent on entertainment for a student who works 10 hours is $30.

(a) To approximate the equation of the line of best fit, you can visually inspect the scatter plot and determine a linear relationship between the number of hours worked (x) and the amount of money spent on entertainment (y). In this case, the approximate equation y≈2x+10 suggests a positive correlation, where for every additional hour worked, the money spent on entertainment increases by approximately $2, with a base spending of $10.

(b) Using the equation y≈2x+10, you can predict the amount of money spent on entertainment for a student who works 10 hours. By substituting x=10 into the equation, you get y≈2×10+10=30. Therefore, the prediction is that a student who works 10 hours would spend approximately $30 on entertainment, based on the linear relationship observed in the data.
