Unformatted text preview: change when moving from one fixed point to another along the line 11. linear functions – y=ax+b; a does not = 0 12. vertical line – x=a 13. horizontal line – y=b 14. parallel lines – same slope and never intersect 15. perpendicular lines – intersect at 90 degree angles and have a negative reciprocal of the slope 16. reciprocal –1/b is called the multiplicative inverse or reciprocal of b. 17. average rate of change – slope of any function over a closed interval of xvalues 18. inverse function – the domain of f is = to the range of f1 and vice versa. This meants that if the function of f is the set of ordered pairs (x,y) then the inverse of f is the set of ordered pairs (y,x)...
