Because the 2 lines are parallel, (5x+5) + 115 need to equal 180.
Solving for X:
5x+5 +115 = 180
5x + 120 = 180
Subtract 120 from each side:
5x = 60
Divide both sides by 5
x= 60/5
X = 12
Answer:
d. Independent-samples t-test
Step-by-step explanation:
The independent samples t-test can be described as a test under which two groups are compared on the mean value of a continuous normally distributed variable.
The independent samples t-test model is based on the assumption that the mean score of the dependent variable is different because the of the impact of the independent variable that differentiates the two groups.
The independent-samples t-test is also known as a parametric test in which the means of two independent groups are compared with the aim of ascertaining if there is statistical evidence that the associated population means are significantly different.
In this question, there are two independent groups which we intend to compare in order to investigate the effect of antidepressants. The first group is the group of people given antidepressant, while the second is another group of people that is given a placebo. This is a perfect example of independent-samples t-test.
Therefore, the correct option is d. Independent-samples t-test. That is, the type of parametric test that should be run in order to investigate the effect of antidepressants by giving one group of people an antidepressant and another group of people a placebo.

We must first find the slope.
<em>Please refer to my Answer from this Questions to know more about Slopes of a Line:</em>
We can see the marked points, and , are on the line.
Solving for the slope:
Now we can now solve for the -intercept.
