Question

# If the regression equation is equal to y = 23.6-54.2 x, then 23.6 is the ______ while -54.2 is the _______ of the regression line.

- Slope, intercept
- Slope, regression coefficient
- Intercept, slope
- Radius, intercept

## The correct answer is: Intercept, slope

### If the regression equation is equal to y = 23.6-54.2 x, then 23.6 is the INTERCEPT while -54.2 is the SLOPE of the regression line.
