Napomena autora:

A complete formative lesson with embedded slideshow, mini lecture screencasts, checks for understanding, practice items, mixed review, and reflection. I create these assignments to supplement each lesson of Pearson's Common Core Edition Algebra 1, Algebra 2, and Geometry courses. See also mathquest.net and twitter.com/mathquestEDU.

Problem 2 Got It? What is the equation of a line with m = 6 and y-intercept (0, 5)?

y = 6x + 5

y = 5

y = 6x

y = 5x + 6

Problem 2 Got It? Reasoning: In the previous item, do you get a different equation if you use (-6, 0) and the y-intercept to find the slope of the line? Explain.

Yes; choosing different points results in a different slope.

No; any two points on a line can be used to calculate the slope.
