Across
- 2. is a special kind of rule that can be expressed using mathematical symbols, such as in an equation.
- 4. is usually used for non-numerical relationships.
- 5. - the graph of a linear equation.
- 7. mean that the line will continue indefinitely in both directions. IN TWO VARIA
- 13. - is the signed distance of the point from the π₯ β axis.
- 14. - is a set of ordered pairs.
- 16. - When a function evaluation leads to a division by zero.
- 19. - each point in the plane corresponds to an ordered pair (π₯, π¦) of real numbers.
- 20. - means how many units you move left or right from point to point.
- 21. diagrams also allow us to see the type of correspondence of a relation more clearly.
- 23. - lines in a plane that are parallel do not intersect and have the same slope.
- 25. - is formed by two real number lines intersecting at a right angle at their 0 coordinates
Down
- 1. - the regions formed on a plane by the axes.
- 3. - is the set of all second coordinates.
- 6. is a relation wherein each element of the domain is paired with exactly one element in the range.
- 8. - is the set of all first coordinates.
- 9. - point of intersection of the coordinate axes; also referred to as point.
- 10. - are negative reciprocals of each other, that is, the product of their slopes, neither of which is vertical, is always -1.
- 11. - An equation of through the point (π, π) is π₯ = π.
- 12. - An equation of through the point (π, π) is π¦ = π.
- 15. - is the signed distance of the point from the π¦ βaxis.
- 17. - is a relation wherein each element of the domain is paired with exactly one element in the range.
- 18. - a linear equation that has solutions with 0 as one coordinate.
- 22. - can be facilitated with the use of a Cartesian coordinate system.
- 24. - means how many units you move up or down from point to point.
