Slope Practice Problems Practice Problem 1: A tree grows at steady rate of 15 inches per day and achieves its full height of inches in 30 days.

Remember a point is two numbers that are related in some way. This can be written as 3, They will be able to solve real-world problems using linear models in point slope form.

NOTE: Also remember, that when identifying a point from a word problem, "time" is always the x-coordinate. Based on your equation, how many participants are predicted for the fifth year? In many cases, we can find the equation of the line by hand, especially for integers.

Now you will have to read through the problem and determine which information gives you two points. In the third year there were 57 participants.
