  • Legend and title

Exploring Mathematical Relationships

The Gizmo provides a powerful tool for exploring different mathematical relationships. For example, users can:

  • Plot linear functions to determine their slope and y-intercept.
  • Create scatter plots to identify correlations and patterns in data.
  • Use bar graphs to compare the distribution of different data sets.
  • Analyze pie charts to understand the relative proportions of different categories.

Answer Key for Common Exercises: Graphing Skills Gizmo Answer Key

This table provides answers and step-by-step solutions for a variety of common exercises that use the Graphing Skills Gizmo.

To use the table, simply find the exercise number that corresponds to the exercise you are working on. Then, read the answer and step-by-step solution to check your work or to learn how to solve the exercise.

Common Exercises

Exercise Number Exercise Description Answer Step-by-Step Solution
1 Graph the following equation: y = 2x + 1 Graph of y = 2x + 1
  1. Find the y-intercept by plugging in x = 0: y = 2(0) + 1 = 1
  2. Plot the point (0, 1) on the y-axis.
  3. Use the slope (2) to find another point on the line. For example, you can move up 2 units and over 1 unit to get the point (1, 3).
  4. Plot the second point and draw a line through the two points.
2 Find the slope of the line that passes through the points (2, 3) and (4, 7) 2
  1. Use the slope formula: m = (y2
    • y1) / (x2
    • x1)
  2. Plug in the coordinates of the two points: m = (7
    • 3) / (4
    • 2) = 2
3 Write the equation of the line that passes through the point (1, 2) and has a slope of

3

 y =

3x + 5
  1. Use the point-slope form of the equation of a line: y
    • y1 = m(x
    • x1)
  2. Plug in the coordinates of the point and the slope: y
    • 2 =
    • 3(x
    • 1)
  3. Simplify the equation: y
    • 2 =
    • 3x + 3
  4. Add 2 to both sides of the equation: y =

    3x + 5
4 Graph the following inequality: y > 2x
