By definition the rate of change of a function is given by:
[tex]AVR = \frac{Change In Y}{Change In X} [/tex]
Or equivalently:
[tex]AVR = \frac{y2 - y1}{x2 - x1} [/tex]
Substituting the values given in the problem we have:
[tex]AVR = \frac{1.5}{18} [/tex]
Rewriting we have:
[tex]AVR = 0.08[/tex]
Answer:
the rate of change of the ramp is:
[tex]AVR = 0.08[/tex]
