Across
- 2. the principal or horizontal axis of a system of coordinates, points along which have a value of zero for all other coordinates.
- 5. an equation between two variables that gives a straight line when plotted on a graph.
- 7. an activity or purpose natural to or intended for a person or thing.
- 9. a surface of which one end or side is at a higher level than another; a rising or falling surface.
- 10. the slope of a horizontal line!
- 11. is a number in an ordered pair that names the location of a point on the coordinate plane
- 13. an inequality which involves a linear function.
- 16. It is formed by a horizontal number line, called the x-axis, and a vertical number line, called the y-axis.
- 18. an equation or function that is the equation of a straight line and takes the form y = mx + b
- 19. a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain
Down
- 1. each of four quarters
- 3. a point on the graph where x is zero.
- 4. the slope of a vertical line!
- 6. The set of values of the independent variable(s) for which a function or relation is defined.
- 8. a function that is not a linear function
- 9. the way of writing the equation of a line so that the slope (steepness) and y-intercept (where the line crosses the vertical y-axis) are immediately apparent.
- 12. the way in which two or more concepts, objects, or people are connected; a thing's effect on or relevance to another.
- 14. where the line crosses the y-axis.
- 15. the secondary or vertical axis of a system of coordinates, points along which have a value of zero for all other coordinates.
- 17. the point or place where something begins, arises, or is derived.
