Question

The two key parts of regression equation involve the______ and the y'________

a. slope; axis
b. asymptote; axis
c. asymptote; intercept
d. slope; intercept

Answer 1

Explanation:

b

Answer 2

d. slope; intercept

Explanation:

A regression equation is represented in the form :

y = mx + c (linear regression)

Where y = predicted variable

m = slope of regression line

x = independent variable

c = intercept (where the regression line crosses the y axis).

For a multiple regression equation where there are more than one independent, then we have multiple slopes

y = c + m1x1 + m2x2 +...mnxn

Hence, the slope. And intercept are the two key part of a regression equation which enables us to make prediction and correlation about the dependent and independent variables.
