Across
  1. 5. The point where the x-axis and y-axis intersect on a graph, denoted as (0,0).
  2. 7. A relationship between two quantities where the ratio of the two remains constant.
  3. 11. The vertical and horizontal lines that define the graph area.
  4. 12. An algebraic representation of a line, usually in the form y=mx+c.
  5. 15. A specific location in space represented by coordinates, usually (x, y).
  6. 17. The form y=mx+c where m represents the slope and c represents the y-intercept.
  7. 18. A straight path that extends in both directions with no end.
  8. 20. A measure of how steep a line is, also known as the slope.
  9. 21. The point where a line crosses the y-axis.
  10. 22. A visual representation of data.
  11. 23. A pair of numbers that determines the position of a point.
Down
  1. 1. A line that runs left to right in a graph.
  2. 2. The equality of two ratios.
  3. 3. Another term for gradient, representing the steepness of a line.
  4. 4. The point where a line crosses the x-axis.
  5. 6. The form ax+by=c for a linear equation.
  6. 8. A symbol, usually a letter, that represents one or more numbers.
  7. 9. A value that does not change.
  8. 10. A line that runs up and down in a graph.
  9. 13. A relation between two variables that forms a straight line when graphed.
  10. 14. The points at which a graph intersects the axes.
  11. 16. To mark or locate a point, line, or figure on a graph or chart.
  12. 19. A line without any curves.
