Across
  1. 3. is a unique point plotted on a Cartesian coordinate plane, where the first value represents the horizontal position relative to the x-axis, and the second value represents the vertical position relative to the y-axis.
  2. 7. is the set of all ordered pairs in the plane that satisfy the equation.
  3. 9. a conventional, normalized way of writing numbers or equations to make them consistent and easier to understand
  4. 13. the horizontal coordinate of a point in a 2D Cartesian coordinate system, representing its distance from the vertical y-axis, measured parallel to the horizontal x-axisaxis.
  5. 14. the primary horizontal number line in a coordinate system, running left-to-right
  6. 17. three or more points that lie on the same single straight line
  7. 19. is a two-dimensional, flat surface formed by the intersection of a horizontal line x-axis and a vertical line y-axis that cross at a point called the origin
  8. 20. a visual representation of data points, functions, or ordered pairs on a coordinate system to illustrate relationships between variables.
  9. 21. an ordered pair or set of numbers, written as or that uniquely identify a specific point's location on a graph
  10. 22. a pair of numbers used to locate a point on a coordinate plane, where the specific order of the numbers matters.
  11. 23. the second number in an ordered pair (x,y)
  12. 25. the first value in an ordered pair ((x,y)
Down
  1. 1. a set of mutually perpendicular, intersecting lines (numbered axes) that form the foundation of a coordinate system,
  2. 2. the primary vertical reference line on a coordinate system,
  3. 4. is one of the four, two-dimensional regions created by the intersection of the horizontal x-axis and vertical y-axis on a coordinate system.
  4. 5. y=mx+b This form makes it simple to graph a line by plotting the y-intercept first, then using the slope to find a second point.
  5. 6. the specific value, or set of values, for a variable that makes an equation or inequality true.
  6. 8. the foundational point of reference where the axes of a coordinate system intersect
  7. 10. are straight lines in a plane that are always the same distance apart and never intersect or cross, no matter how far they are extended
  8. 11. the point where a graph crosses the vertical y-axis,
  9. 12. an algebraic equation where each term is either a constant or a variable with an exponent of exactly 1
  10. 15. the vertical change divided by the horizontal change.
  11. 16. the primary vertical, numerical reference line in a coordinate system
  12. 18. the primary horizontal, numerical reference line in a coordinate system
  13. 24. the vertical coordinate in a coordinate system
  14. 25. the point where a graph crosses the vertical x-axis,
