Regents Exam: Algebra I August 2016 (Problem 15 of 37)

The video tutorial guides viewers through determining which of four functions has a constant rate of change of -3. Each function is represented differently: tabular, ordered pairs, graphical, and equation form. The tutorial systematically calculates the slope for each option, eliminating those that do not match the required slope. Ultimately, option 4 is confirmed as the correct answer by rewriting its equation in slope-intercept form, revealing a slope of -3.

What is the constant rate of change that we are looking for in the functions?

How do we determine the slope of a function represented in tabular form?

What was the slope calculated for option 1, and was it equal to negative 3?

What conclusion can we draw about option 2 after checking the slope?

How do we find the slope of the function in option 4, and what is the result?
