If the intercept value of a linear regression model is 40, the slope value is 40, and the value of X is 40, which of the following is the resulting forecast value using this model?
A) 120
B) 1,600
C) 1,640
D) 2,200
E) 64,000

Quizplus · Accepted Answer

Using the equation for a linear regression model:

y = intercept + slope(x)

We can substitute in the given values:

y = 40 + 40(40)
y = 1,640

Therefore, the resulting forecast value using this model is 1,640, which is answer choice C.
