  1. 3. The expressions where any two values are compared by the inequality symbols such as, '<', '>', '≤' or '≥'.
  2. 4. A mathematical representation of a network and it describes the relationship between lines and points.
  3. 7. An assignment of values to the unknown variables that make the equality in the equation true.
  4. 8. A straight one- dimensional figure that has no thickness and extends endlessly in both directions.
  5. 14. A relation that expresses the comparison between the combination of both unequal and equal quantities
  6. 15. A pair of elements a, b having the property that ( a, b)
  7. 16. The system of marks at fixed intervals, which define the relation between the units being used and their representation on the graph
  8. 18. A two-dimension surface formed by two number lines. One number line is horizontal and is called the x-axis. The other number line is vertical number line and is called the y-axis. The two axes meet at a point called the origin.

  1. 1. A location that is represented by a dot.
  2. 2. identifies the outer edge (or outline) of a shape or area. This could be a geometric shape or an inequality graph.
  3. 5. A planar region consisting of all points on one side of an infinite straight line, and no points on the other side.
  4. 6. The y-coordinate of a point where a line, curve, or surface intersects the y-axis.
  5. 7. The equation of a straight line in the form y = mx + b where m is the slope of the line and b is its y-intercept.
  6. 9. The set of values that satisfy a given set of equations or inequalities.
  7. 10. A graphical technique for representing a data set, usually as a graph showing the relationship between two or more variables.
  8. 11. A Cartesian coordinate system in a plane is a coordinate system that specifies each point uniquely by a pair of numerical coordinates
  9. 12. A quantity that may change within the context of a mathematical problem or experiment.
  10. 13. A relation that holds between two values when they are different
  11. 16. Numerical measure of a line's inclination relative to the horizontal
  12. 17. equation An algebraic equation of the form y=mx+b. involving only a constant and a first-order
