Note from the author:
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. The outlined content above was added from outside of Formative. 1

Review Lesson 5-5: Identify the form of each equation.
• slope-intercept form
• point-slope form
• standard form
• none of these
• 5x + 3y = 21
• y = -7x + 1
• x = 5 + 3y
• y = -9(x + 2)

Review Lesson 5-5: Is the equation in standard form? Explain.
Yes, the equation is in standard form. It is in the form Ax + By = C, A, B, and C are real numbers, and A and B are not both zero.
No, the equation is not in standard form. Standard form is y = mx + b.
No, the equation is not in standard form. -2 is not a real number.

Review Lesson 5-5: Match each equation from the left column with its equivalent standard form equation in the right column.
• y = 4x + 7
• y + 3 = 2(x - 5)
• x = 6y + 3
• 2y + 4x = 8
• -2x + y = -13
• x - 6y = 3
• -4x + y = 7
• 4x + 2y = 8 34
