The domain of the relation is 7,13 and the range of the relation is 4,20. I hope this helps.
1) This sequence of numbers is arithmetic, because each number is the previous one divided by two.
2) the next number in the sequence is 125/2, which is 62.5
Based on the information given, the explanatory variable will be the SAT prep program and the response variable is the student's scores.
<h3>
Identification of the variables.</h3>
The information given is that the researcher conducts an experiment to investigate whether an SAT prep program would improve students' scores on the SAT.
The explanatory variable is the factor that is manipulated by the researcher. The response variable is the result of the experiment.
In this case, the explanatory variable is the SAT prep program and the response variable is the student's scores.
In this case, the treatment will be the 120 students that took part in the research. They're the ones that are exposed to manipulation by the researcher.

Answer:
y = 3/5x + 5
Step-by-step explanation:
Gradient of the line


y = 3/5x + c
Substitute either point in to find c
y = 3/5x + c at (0,5)
5 = 3/5(0) + c
5 = 0 + c
5 = c
y = 3/5x + c at (-5,2)
2 = 3/5(-5) + c
2 = -3 + c
2 + 3 = c
5 = c
y = 3/5x + c
Replace c with 5
y = 3/5x + 5
