Across
- 1. The most common value in a collection
- 8. A straight line, or an equation or expression whose graph is a straight line.
- 9. An equation with four or more terms.
- 12. An equation with two terms.
- 13. A mathematical sentence that uses one of the symbols <, >, ≤, or ≥.
- 14. The top number or expression in a fraction.
- 16. An image formed by plotting the solutions to an equation or inequality, or some other set of pairs of numbers, on a coordinate plane.
- 18. The average of a collection of data values. This can be computed by adding all the values and then dividing by the number of values.
- 19. The process of eliminating the variables in order to solve an equation.
- 20. An equation with three terms.
Down
- 2. The bottom number or expression in a fraction.
- 3. The process of substituting the variables in order to solve an equation.
- 4. A number that measures how steep a line is. It shows the amount of change in the height of the line as you go 1 unit to the right. The equation for this line is y=mx+b.
- 5. Each of the four sections of a coordinate plane made by the intersecting x- and y-axes. The four sections are labeled I, II, III, and IV, counterclockwise from the top right.
- 6. An equation with one term.
- 7. The horizontal line running through the origin on a coordinate plane.
- 10. The middle number in an ordered list of data values. If there are an even number of values, it is halfway between the two middle numbers in the list.
- 11. A letter (like x) that we can use to mean different numbers at different times.
- 15. In a power, the number of times the base is multiplied by itself.
- 17. The vertical line running through the origin on a coordinate plane.
