Answer to Problem 5E
Linear model
Explanation of Solution
Given information:
To determine if the given graph can be modeled by linear model, quadratic model or neither of them, try to draw a straight line or a parabola through the given scatter plot.
If a straight line can be drawn through the points of the scatter plot, it could be modeled by linear model whereas if a parabola can be drawn through the points of the scatter plot, it could be modeled by a quadratic model.
In case if both are not possible, it could neither be modeled.
Here, in the given graph we could draw a straight line. Therefore, the scatter plot could be modeled by a linear model.
Conclusion:
Therefore, given scatter plot is modeled by linear model.
