Across
- 4. on a graph, the line that holds the independent variables
- 5. two lines that have the same slope
- 7. Refers to the point where the line crosses either axis
- 11. when both lines intersect at 90 degrees
- 12. progressing from one stage to another in a series, sequently
- 13. A change in one variable corresponding to a change in another
- 14. There is no y-intercept but the equation passes through the origin
- 16. a diagram showing the relation between variable quantities
- 18. on a graph, the line that holds the dependant variables
- 20. Direct and partial variations are examples of what

- 23. the mathematical equation used to measure the steepness of a line
Down
- 1. a straight strip typically used to draw straight lines or to measure distance
- 2. when an equation is containing a variable with an exponent other then one
- 3. The number it would be when at zero or x=0
- 6. a group of numbers used to indicate the position of a point or line
- 7. When there is a y-intercept but does not pass through the origin
- 8. When the numerator and denominator of a fraction is switched
- 9. A method used to help us determine if a relation is linear
