That is false. The slope is -2.
Answer:
By making use of a lower confidence level
Step-by-step explanation:
The margin of error is also referred to as the confidence interval and it is the system in which we use to measure the error in the result of the survey or experiment.
Now, for us to reduce the margin of error, there are different things we can do such as;
- increasing sample size
- using less data variation
- making use of a lower confidence level
- making use of a one sided confidence interval rather than a two sided confidence interval.
Looking at the above different methods of making the margin of error smaller, the one that is always under the control of the researcher is "making use of a lower confidence level".
Every other means, he does not have as much control as he has to do to lower the confidence level. That one is strictly based on his jurisdiction.

<u>Note</u>: From visual inspecton of the graph shown — [Note: all images attached refer to the same graph.] :
→ We can see that when "x = -2" ; there is only one value for "y" ; and then the "line" of the graph stops for any coordinate corresponding to any "x-value" LESS THAN "-2" ;
→ and that there are corresponding "y-coordinates" corresponding to any "x-value that is equal to "-2" and "GREAT THAN "-2" .
