Across
- 1. An image formed by plotting the solutions to an equation or inequality, or some other set of pairs of numbers, on a coordinate plane. To graph an expression containing the variable x, set y equal to that expression.
- 8. Rewriting an expression as a product.
- 10. A mathematical sentence with an equals sign (like 3x+5=11).
- 11. The distance a number is from 0.
- 13. The point on a coordinate plane where the x-axis and y-axis intersect. It is represented by the coordinates (0,0).
- 14. The bottom number or expression in a fraction.
- 15. More than any finite (real) number.
- 16. The values of x where an expression is zero. These are the x-coordinates of the x-intercepts of the expression’s graph. For a polynomial expression, these are usually called roots.
Down
- 2. A sum of monomials. Usually terms with higher powers are written first.
- 3. A letter (like x) that we can use to mean different numbers at different times.
- 4. In an expression or equation, eliminating a variable by replacing it with another expression that it is equal to.
- 5. A constant that a variable or expression is multiplied by.
- 6. A fractional quantity written with a decimal point (like 0.5).
- 7. A location in the coordinate plane. A point has coordinates (x,y), where x is given by the labels below a coordinate grid, and y is given by the labels to the left of a coordinate grid.
- 9. The set of outputs (y-coordinates) of a relation or function.
- 12. 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 slope of the line y=mx+b is m.
