Across
- 4. the set of values assigned to the independent variables of a function.
- 7. an algebraic expression obtained by adding, subtracting and /or multiplying real numbers and variables.
- 9. A rule that assigns to each input exactly one output.
- 11. An angle that measures less than 90°.
- 14. A point where a line or curve meets the vertical axis (the y-axis). The y-intercept of the line y=mx+b is the point (0,b).-legged bug that spins webs
- 15. two quantities written in such a way as to indicate that one quantity precedes or is to be considered before the other coordinate plane where the x-axis and y-axis intersect
- 16. A point on a 2-dimensional plane is described by a pair (x,y).
- 19. contain the same variable which is raised to the same power
- 20. Two equations that both impose conditions on the variables. An ordered pair is a solution of the system if and only if it is a solution of each of the given equations.
- 22. Rigid motion around a fixed center A, with turning but no reflection.
- 24. The horizontal line running through the origin on a coordinate plane.
- 25. The form y=mx+b for a linear equation, where m and b are constants.
- 26. A 2-dimensional flat surface used for plotting points, lines, curves, and regions. It contains an x and a y axis which intersect at the origin.
Down
- 1. Two angles whose total measure is 180°.
- 2. A solution to an equation with variable x is a number that, when substituted for x, makes the two sides of the equation equal
- 3. A constant that a variable or expression is multiplied by.
- 5. The point on a coordinate plane where the x-axis and yaxisintersect It is represented by the coordinates (0,0).
- 6. Rigid motion across a fixed line AB in a plane, like a mirror image.
- 8. what comes out of the function
- 10. Two angles whose total measure is 90°
- 12. A letter (like x) that we can use to mean different numbers at different times.
- 13. The vertical line running through the origin on a coordinate plane.
- 17. a system of symbols or signs that denote elements such as phrases, numbers, words
- 18. a symbol or a combination of symbols used in algebra, containing one or more numbers, variables, and arithmetic operations
- 21. If (x1, y1) and (x2, y2) are two points on a line, then its the ratio m = rise/run = y/x = (y2−y1)/(x2−x1) provided x2 ≠ x1
- 23. In a power, the number of times the base is multiplied by itself.
