Systems

6. A system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. The solution of such a system is the ordered pair that is a solution to both equations (where the lines intersect).
9. restrictions (limitations, boundaries) that need to be placed upon variables used in equations that model real-world situations.
10. is dashed for > and < and solid for ≥ and ≤. It is used to display the solutions to a system of inequalities on a graph.

1. To solve a system of equations by elimination we transform the system such that one variable "cancels out". ... In order to solve for y, take the value for x and substitute it back into either one of the original equations.
2. a set of two or more inequalities in one or more variables. The solution to a system of linear inequality is the region where the graphs of all linear inequalities in the system overlap.
3. Intecept form of two-variable linear equations, and how to interpret it to find the slope and y-intercept of their line.
4. works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other.
5. will lie in one of the half-planes formed by the boundary line. If the test point makes the inequality true, shade that side of the line (shading over the point).
6. (to a linear inequality)Any point that makes the inequality true.
7. a statement that asserts the equality of 2 expressions, which are connected by the equals sign.
8. a symbol that works as a placeholder for expression or quantities that may change.
