  1. 2. A measurement of the steepness of a line in the coordinate plane; represented by the letter "m."
  2. 3. A line parallel to the x-axis
  3. 5. A line parallel to the y-axis
  4. 8. Any function that can be defined by a linear equation, and usually written in the form y = mx + b
  5. 12. A relationship between two variables where their ratios are equivalent
  6. 13. A number used to multiply a variable
Down
  1. 1. A linear equation in the form y = mx + b, where m is the slope of the line and b is the y-intercept
  2. 4. The point at which a line crosses the y-axis
  3. 6. The point where the x-axis and y-axis intersect
  4. 7. An input-output relationship that has exactly one output for each input
  5. 9. The point(s) at which a line crosses the x-axis
  6. 10. A term in an that does not contain any variables; just a number
  7. 11. A ratio that compares the change in values of the y variables to the change in values of the x variables
