3. Ordered Pair
Two numbers written in a certain order. Usually written in parentheses like this: (4,5) Can be used to show the position on a graph, where the "x" (horizontal) value is first, and the "y" (vertical) value is second.

4. Point of Intersection
The point at which two lines cross or meet

5. Consistent
A system of equations with at least one ordered pair that satisfies both equations.

6. Inconsistent
A system that has no solution

7. Independent
A system of equations with exactly one solution

8. Dependent
A system of equations that has an infinite number of solutions; lines coincide when graphed

9. Slope
The slope of a line is a number that measures its "steepness", usually denoted by the letter m. It is the change in y for a unit change in x along the line.

10. X-intercept
The x-intercept of a line is the point at which the line crosses the x axis. ( i.e. where the y value equals 0 ) x-intercept = ( x, 0 )
The point (-1,0)

11. Y-Intercept
The y-intercept of a line is the point at which the line crosses the y axis. ( i.e. where the x value equals 0 ) y-intercept = ( 0, y )
The point (0,1)

12. Domain The x values The values of the independent variable
The input values
In the ordered pairs:
(1, 2), (3, 4), (5, 9), (6, 11)
The domain is: 1, 3, 5, 6

13. In the ordered pairs: (1, 2), (3, 4), (5, 9), (6, 11)
Range
The y values
The values of the dependent variable
The output values
In the ordered pairs:
(1, 2), (3, 4), (5, 9), (6, 11)
The range is: 2, 4, 9, 11
