Massachusetts 2009 Spring Release, Mathematics - Grade 10 Question 29: Multiple Choice Reporting Category: Patterns, Relations, and Algebra Standard: 10.P.2 Demonstrate an understanding of the relationship between various representations of a line. Determine a line’s slope and x- and y-intercepts from its graph or from a linear equation that represents the line. Find a linear equation describing a line from a graph or a geometric description of the line, e.g., by using the “point-slope” or “slope yintercept” formulas. Explain the significance of a positive, negative, zero, or undefined slope. The slope of a line is . The line contains the point (6, 5).
