Across
- 3. A type of data or graph with an unbroken line or curve. It involves measuring quantities where any value in between is possible (e.g., time, height, temperature).
- 5. This is how we give the answer to all systems of equations problems.
- 7. The specific overlapping shaded area on a graph where all constraints or inequalities in a system are true at the same time. Any coordinate inside this area is a valid solution.
- 9. The vertical number line on a coordinate plane. It moves up and down, representing the output value (y), and sits where the horizontal value is exactly zero (x=0).
- 10. A collection of two or more inequalities with the same variables. Instead of intersecting at a single point, their solution is an entire overlapping area of points on a graph.
- 11. A function whose graph forms a straight line. It changes at a constant rate and the variables are always raised to the first power.
Down
- 1. A feasible region that is completely enclosed by boundary lines, forming a closed geometric shape like a polygon. It has fixed limits and can be completely contained within a circle.
- 2. A feasible region that is open and extends infinitely in at least one direction. It cannot be enclosed because it goes on forever without a boundary closing it off.
- 4. A collection of two or more equations with the same set of variables. The solution is the exact point(s) where the graphs intersect and make all equations true at the same time.
- 6. When you combine two terms and the result is zero.
- 8. The horizontal number line on a coordinate plane. It moves from left to right, representing the input value (x), and sits where the vertical value is exactly zero (y=0)
