Graphs

Parts of a Graph -

X Axis – Independent Variable - Origin Y Axis – Dependent Variable -

Setting up a graph Relationship between hours worked and pay Independent Variable – Working Hours Dependent Variable – Pay

Graphing – Hours worked & Paycheck Time Worked (hours) Pay (dollars) When hours worked is low pay is low When hours worked is high, pay is high Direct Relationship

-

Inverse or Indirect Relationship X Axis Y Axis Temperature Density -  -

Cyclic (Cycle) Relationship Time (hours) Tides Low High -

Constant – No change-Static Travel from the Earth to the Moon Mass -

Non-Sense Graph DO NOT PICK – NOT POSSIBLE

Rate of Change - Rate of Change = Change in Field Value Change in Time

Graphing – Hours worked & Paycheck Time Worked (hours) Pay (dollars) What is the rate of change between these two points?

Example 21 Dollars 3 Hours 7 Dollars/Hours (28 – 7) Dollars (4-1) Hours

Example A B C D What is the rate of change from point A to point B Years (1986 = 1) Number of Cell Phone Users

(3000–1000) Users (4-2) Years Example (A-B) 2000 Users 2 Years 1000 Users/Year

Example A B C D What is the rate of change from point B to point C Years (1986 = 1) Number of Cell Phone Users

(14,000–3,000) Users (7-4) Years Example (B-C) 11,000 Users 3 Years 3,667 Users/Year

Example (C-D) What is the rate of change between Points C and D?

Extrapolation X Axis Y Axis Temperature Density -

Interpolation X Axis Y Axis Temperature Density -

Equilibrium - - Dynamic

Example – Oceans are constantly evaporating, why is the ocean level remaining constant?
