  1. Vocabulary Chapter 5

  2. The phrase meaning the relationship between two changing quantities is the

  3. Rate of change.

  4. The ratio for the vertical change(or rise) to the horizontal change or (run) is called the

  5. Slope.

  6. A relationship that can be represented by a function in the form y = kx is called a

  7. Direct variation.

  8. An equation that models a linear function is called a

  9. Linear equation.

  10. The slope-intercept form of a linear equation is given by

  11. y = mx + b

  12. The point-slope form of a linear equation is given by

  13. y – y₁ = m(x - x₁)

  14. The standard form of a linear equation is given by

  15. Ax + By = C

  16. The x- and y-coordinates where a graph crosses the x- and y-axis are called the

  17. x- and y-intercepts

  18. Lines in the same plane that do not intersect are called

  19. Parallel lines

  20. Lines that intersect to form right angles are called

  21. Perpendicular lines

  22. Two numbers whose product is -1 are called

  23. Opposite reciprocals

  24. The slopes of parallel lines are

  25. Equal

  26. The slopes of perpendicular lines are

  27. Opposite reciprocals

  28. A graph that relates two different sets of data by displaying them as ordered pairs is called a

  29. Scatter plot

  30. A line on a scatter plot, drawn near the points, that shows a correlation is called a

  31. Trend line

  32. Using a trend line to estimate a value between known values is called

  33. Interpolation

  34. Using a trend line to estimate values outside the range of known values is called

  35. extrapolation

  36. The trend line that shows the relationship between two sets of data the most accurately is called the

  37. Line of best fit

  38. Functions that have V-shaped graphs that open up or down are called

  39. Absolute value functions

  40. A shift of a graph horizontally, vertically, or both is also called a

  41. Translation
