4. Solution of Linear Equation
5. A plane formed by the intersection of a horizontal number line and a vertical number line.
9. The change in x between any two points on a line.
10. The change in y between any two points on a line.
11. The distance between a number and 0 on a number line; The absolute value of a number a is written as |a|.
14. The form is Ax+By=C, where A and B are not both zero
16. A linear equation written in the form y-1₁=m(x-x₁); The graph of the equation is a line that passes through the point (x₁,y₁), and has the slope m.
17. The four regions created by the intersection of the horizontal and vertical number lines in a coordinate plane.

1. An equation whose graph is a line y=x-1.
2. The x-coordinate of the point where a line crosses the x-axis.
3. Numbers that are greater than 0.
4. A linear equation written in the form y=mx+b; The graph of the equation is a line that has a slope of m and a y-intercept of b.
6. The point, represented by the ordered pair (0,0), where the horizontal and vertical number lines intersect in a coordinate plane.
7. The y-coordinate of the point where a line crosses the y-axis.
8. The value of a ratio of the change in y (the rise) to the change in x (the run) between any two points on a line, Slope is measure of the steepness of a line.
12. ordered pair (x,y) that makes an equation true.
13. Numbers that are less than 0.
15. Two numbers that are the same distance from 0 on a number line, but on opposite sides of 0.
