Math Problem Statement

Create stacks that show the same constant rate of change.

Solution

The task seems to involve finding shapes, graphs, and tables that share the same constant rate of change (which could mean the slope of a linear equation or the ratio between dimensions for triangles). Let's break down the image:

  1. Triangles: The slope of a triangle can be calculated by using "rise over run" (height divided by base).

    • Triangle 1: Height = 6, Base = 2, so slope = 62=3\frac{6}{2} = 3.
    • Triangle 2: Height = 6, Base = 3, so slope = 63=2\frac{6}{3} = 2.
    • Triangle 3: Height = 8, Base = 2, so slope = 82=4\frac{8}{2} = 4.
    • Triangle 4: Height = 2, Base = 8, so slope = 28=0.25\frac{2}{8} = 0.25.
  2. Tables: The rate of change in tables is the difference in y-values divided by the difference in x-values (the slope of a line).

    • Table 1: (x, y) values: (1,3),(2,1),(3,1),(4,3),(5,5),(6,7)(1, 3), (2, 1), (3, -1), (4, -3), (5, -5), (6, -7), so the slope = 7361=2\frac{-7 - 3}{6 - 1} = -2.
    • Table 2: (x, y) values: (1,2),(2,1),(3,4),(4,7),(5,10),(6,13)(1, -2), (2, 1), (3, 4), (4, 7), (5, 10), (6, 13), so the slope = 13(2)61=3\frac{13 - (-2)}{6 - 1} = 3.
    • Table 3: (x, y) values: (1,5),(2,5.25),(3,5.5),(4,5.75),(5,6),(6,6.25)(1, 5), (2, 5.25), (3, 5.5), (4, 5.75), (5, 6), (6, 6.25), so the slope = 6.25561=0.25\frac{6.25 - 5}{6 - 1} = 0.25.
    • Table 4: (x, y) values: (1,12),(2,8),(3,4),(4,0),(5,4),(6,8)(1, 12), (2, 8), (3, 4), (4, 0), (5, -4), (6, -8), so the slope = 81261=4\frac{-8 - 12}{6 - 1} = -4.
  3. Graphs: The slope of a graph can be identified based on the inclination of the line.

    • Graph 1: Downward slope, slope = -2.
    • Graph 2: Upward slope, slope = 3.
    • Graph 3: Very gentle upward slope, slope = 0.25.
    • Graph 4: Downward slope, slope = -4.

Now, we can group them by matching slopes:

  • Slope = 3: Triangle with height 6, base 2; Table 2; Graph 2.
  • Slope = -2: Table 1; Graph 1.
  • Slope = 0.25: Triangle with height 2, base 8; Table 3; Graph 3.
  • Slope = -4: Triangle with height 8, base 2; Table 4; Graph 4.

You can create stacks by placing the matching items together based on their slope.

Would you like a detailed step-by-step on calculating any particular group's slope?


Relative questions:

  1. How do you calculate the slope of a triangle?
  2. What is the formula for determining the slope between two points on a table?
  3. How do positive and negative slopes differ visually on a graph?
  4. Can two different triangles have the same slope if their dimensions are proportional?
  5. How does the constant rate of change help in identifying linear relationships?

Tip: The slope represents how steep a line is and whether it increases or decreases as you move from left to right.
