  1. 2. a mathematical statement that two expressions are equivalent
  2. 3. the x coordinate of the point where the graph crosses the x axis
  3. 5. the ratio of the difference in y-values to the difference in x-values between any two different points on the line
  4. 11. a set of functions whose graphs have basic characteristics in common. Functions in the same family are transformations of their parent functions
  5. 13. the y coordinate of the point where the graph crosses the y axis.
  6. 14. a pair of numbers (x,y) that can be used to locate a point on a coordinate plane/ The first number x indicates the distance to the left or right of the origin and the second number y indicated the distance above or below the origin
  7. 16. the difference in the y values of two points on a line
  8. 17. equation: any equation that can be written in standard form ax + by = c where a,b, and c are real numbers and a and b are not both 0
  9. 18. a function that can be written in the form y=mx+b, where x is the independent variable and m and b are real numbers. Its graph is a line.
Down
  1. 1. y = mx + b
  2. 4. a ratio that compares the amount of change in a dependent variable to the amount of change in an independent variable
  3. 6. the simplest function with the defining characteristics of the family. Functions in the same family are a transformation of their parent function.
  4. 7. a relation in which every domain value is paired with exactly one range value
  5. 8. the difference in the x values of two points on a line
  6. 9. the measure of steepness of a line. rise/run
  7. 10. One of the constants in a function or equation that may be changed. Also, the third variable in a set of parametric equations.
  8. 12. form ax + by = c where a,b, and c are real numbers and a and b are not both 0
  9. 15. the set of points in a coordinate plane with coordinate (x,y) where it is in the domain of the function f and y = b
