System of Equations

3. A type of system that has two visible lines on the graph.
9. Method, Method of solving a system in which two equations are added together in a manner that will eliminate one of the two variables.
11. Two lines cross at a point called an intersection.
13. A type of system that has a solution.
14. The rate at which the y value of a linear function rises or falls as x increases.

1. Two lines that are co-planar and intersect to form four right angles are called perpendicular lines.
2. A type of system that has only one visible line on the graph.
4. Two lines that are co-planar and never intersect are called parallel lines.
5. Method, A method for solving a system of linear equations in which the equivalent expression of a variable is substituted for that variable into the other equation.
6. A type of system that does not have a solution.
7. The number that is multiplied by the variable; 3x has a coefficient of 3.
8. Inequality, An inequality that when graphed will form a line that divides the coordinate plane into a shaded region and unshaded region.
10. Equation, An equation that when graphed will form a line.
12. to a System, The point of intersection for a system of equations.
