Question
Given a simple linear regression model with the following equation: y = b0 + b1x where y is the dependent variable, x is the independent variable, b0 is the y-intercept, and b1 is the slope. If b0 = -3 and b1 = 2, what is the predicted value of y when x = 4?
Expert Solution
Step 1

The predicted value of y when x = 4 can be calculated as follows: 

y = b0 + b1x 

y = -3 + 2 * 4  y = 5 

So, when x = 4, the predicted value of y is 5.
