Slope Assessment and Regression Analysis

In table 4.1 of your text, an equation was estimated after applying regression analysis techniques on the data of A, B, C, D sets of Y = 3 + 0.5X.

What does 3 and .5 mean? Is this slope positive or negative? Is the slope positive or negative of the equation Y = 5 â?" 0.3X? How can you quickly tell whether or not it is a positive or negative curve? What does the Intercept mean? (Hint: remember your linear math studies of Y = mx + b). Respond to at least two of your fellow students' postings.

In general, for equations of the form Y = mx + b, m is the slope of the line, and b is the y-intercept. The slope represents how steep the ...
