Line Graphing Practice

manipulated independent x-axis M I X D R Y Y-axis dependent responding

Determine the Independent and Dependent Variables Time (sec) Speed km/sec 1 10 2 15 3 35 4 45 Independent Variable: Time (sec) Dependent Variable: Speed km/sec

Determine the scale of the x-axis if the grid is 10 boxes wide. Day Height (cm) 1 5 2 8 3 12 4 20 Scale ≥ Range # of boxes Scale ≥ 4 = 0.4  0.5 10

Determine the scale of the y- axis if the grid is 10 boxes high Scale ≥ Range # of boxes Scale ≥ 20 = 2 10

Determine the Interval of the x- axis if the grid is 12 boxes wide Time (hrs) Temperature( ˚C) 12 1 18 2 20 3 21 4 23 5 25 Ix ≥ 5 = 0.42  0.5 12

Determine the interval of the y-axis if the grid is 15 boxes high. Ix ≥ 25 = 1.67  2 15

Describe the Graphing Relationship Cyclic: Temperature goes through a cycle as time goes on, repeating itself. Temperature Time in Hours

Describe the Graphing Relationship Direct Relationship: As the hours spent studying increase, so does the grade on the test.
