New data collected on roller coasters, comparing height of the initial drop to the speed of the coaster, found that the regression line equation is actually y = 0.502 + 12.250

Part A: What is the predicted speed for a drop of 100 feet?

Part B: What would be the predicted speed for a drop of 500 feet?

Part C: Do you think it is likely that a roller coaster will reach the speed found in Part B?

algebra nation question

Part A:62.45

Part B:263.25

Part C:No it's not likely it is impossible for a roller coaster to travel at this speed.

I also had this as a algebra nations question.
