Use the table to answer the question ex-5y3x -4y4 X -3y7 use the spreadsheet calculator to determine the least square regression line for the points in the table round to the nearest hundredth if necessary

It seems like you're asking for help with finding the least squares regression line based on specific points from a table. However, you didn't provide the actual data points or table for me to analyze.

To calculate the least squares regression line, you typically need a set of points in the form of (x, y). Once you have the data, you can follow these steps:

  1. Calculate the means of x and y. \[ \bar{x} = \frac{\Sigma x}{n}, \quad \bar{y} = \frac{\Sigma y}{n} \] where \(n\) is the number of points.

  2. Calculate the slope (m) of the regression line. \[ m = \frac{\Sigma (x_i - \bar{x})(y_i - \bar{y})}{\Sigma (x_i - \bar{x})^2} \]

  3. Calculate the y-intercept (b) of the regression line. \[ b = \bar{y} - m\bar{x} \]

  4. Formulate the least squares regression line equation. \[ y = mx + b \]

If you can provide the data points or table you're referring to, I can assist you further with the specific calculations to find the least squares regression line and round to the nearest hundredth if necessary.
