I'm trying to answer this question:

What is the Variance Inflation Factor for the coefficient of the x variable?

I've been given:

Correlation of x and y = -0.042

R^2 from a previous part of the question is 0.935

K predictor variables = 2

sd of Y = 3.25

I think i should be doing 1/1-R^2k but can't figure out what k is supposed to be or how to tackle this question.

thank you in advance.
