Question

In the mathematical Equation of Linear Regression Y = β1 + β2X + ϵ, (β1, β2) refers to __________

(a) (X-intercept, Slope)

(b) (Slope, X-Intercept)

(c) (Y-Intercept, Slope)

(d) (slope, Y-Intercept)

I have been asked this question in homework.

I want to ask this question from Linear Regression in division Commands, Packages, Visualizing Data and Linear Regression of R Programming

Answer 1

Correct choice is (c) (Y-Intercept, Slope)

To explain: Y-intercept is β1 and X-intercept is – (β1 / β2). Intercepts are defined for axis and formed when the coordinates are on the axis.
