  1. 3. is the slope and b is the y-intercept of the equation's graph
  2. 5. a nonvertical line is the ratio of the vertical change.
  3. 6. a graph is the y-coordinate of a point where the graph crosses the y-axis.
  4. 7. provided y= ax and a=0.
  5. 10. is the most basic linear function in the family: f(x)=x is the parent linear function.
  6. 11. If b2=a, then b is a square root of a.
  7. 12. a graph is the x-coordinate of a point where the graph crosses the x-axis.
  8. 15. of a linear of the equation Ax+By=C
  9. 17. that is, provided the graph of the equation is not a vertical line.
  10. 19. is a number a/b where a and b are integers and b 0.
  11. 20. a number a and it's opposite is 0.
  12. 21. a change in one quantity to a change in another quantity.
  13. 22. is a group of functions with similar characteristics.

  1. 1. the square root of a perfect square is an integer.
  2. 2. The number 0 is the additiveidentity
  3. 4. y is said to vary directly with x.
  4. 8. if they do not intersect. Because slope gives the rate at which a line rises or falls.
  5. 9. have seen linear functions written in the form y=mx+b.
  6. 13. has a hypothesis and a conclusion.
  7. 14. is the set if all rational and irrational numbers, as ilustrated in the Venn diagram below.
  8. 16. is to divide the coordinate plate into four regions called quadrants, labeled I, II, III, and IV as shown.
  9. 18. is a number that cannot be written as a quotient of two integers.
