Challenge Problems
Push your limits with advanced challenges
You are given a set of coordinates: (1, 3), (2, 5), (3, 7). Provide the linear equation that represents this set of data. Then, calculate the slope and intercept.
💡 Hint: Look for the change in y relative to the change in x.
Consider data representing a non-linear relationship posted as y = 4e^(0.5x). Transform it to fit a linear regression model and express the new linear model.
💡 Hint: Focus on finding a linear relationship with transformations.
