To find the least squares line, we need to use linear regression. The equation for the least squares line is y = mx + b, where m is the slope and b is the y-intercept. Using regression analysis, we find that the slope (m) is -0.18 and the y-intercept (b) is 5.90. Therefore, the equation for the least squares line is y = -0.18x + 5.90, which is choice C. Based on the given data, the slope of the least squares line is negative (-0.18) and the y-intercept is positive (5.90). Therefore, the correct equation for the least squares line is y = -0.18x + 5.90, which corresponds to choice C.
