A company hires you to develop a linear regression forecasting model. Based on the company's historical sales information, you determine the intercept value of the model to be 1,200. You also find the slope value is minus 50. If, after developing the model, you are given a value of X = 10, which of the following is the resulting forecast value using this model?
A) −1,800
B) 700
C) 1,230
D) 1,150
E) 12,000

The forecast value using the linear regression model is calculated with the formula Y = intercept + (slope * X). Substituting the given values: Y = 1,200 + (-50 * 10) = 1,200 - 500 = 700.
