What is the relationship between Rabbits and Years for the following example: GRAPH IT YEAR # of RABBITS

ANALYZE your DATA Step One: Identify your problem: What is the relationship between the years and the number of rabbits

Step Two: Draw your Axis Y-axis X-axis

Step Three: Label Your X Axis: Y-axis X-axis What is the relationship between years the number of rabbits Years r

Step Three: Now Label Your Y Axis: Y-axis X-axis What is the relationship between years and the number of rabbits YEARS RABBITS r

Step Three: Now Label Your Y Axis: Y-axis X-axis Was there enough room to label your y axis completely for this problem? YEARS RABBITS r

Step Four: Now Plot Your Points Y-axis X-axis Years RABBITS

Step Four: Now Draw Your LINE Y-axis X-axis Yearss RABBITS

Step Five: Answer the Problem Y-axis X-axis Years RABBITS What are the characteristics of the Red Star?

Step Five: Answer the Problem Y-axis X-axis Years RABBITS What is the x coordinate and the y coordinate of the red star?

Step Five: Answer the Problem Y-axis X-axis Yearss RABBITS r What is the x coordinate and the y coordinate of the green dot

Step Five: Answer the Problem Y-axis X-axis Years RABBITS What are the characteristics of the Green Star?
