Selective serotonin reuptake inhibitor. Selective serotonin reuptake inhibitors (SSRIs), also known as serotonin-specific reuptake inhibitors or serotonergic antidepressants,[1] are a class of drugs that are typically used as antidepressants in the treatment of major depressive disorder and anxiety disorders.
Then you're looking for the midpoint! The midpoint of a line segment is the point located midway between the endpoints of the line segment. This tutorial tells you about the midpoint of a line segment.
Yup! The midpoint between two points is just the average of the x-coordinates and the average of the y-coordinates. Let's look at a few more examples to illustrate that point. For example, in the graph below, the yellow dot is again located at the midpoint between two red points. Those points are located at (3,5) and (-4,-9). Their midpoint is located at (-.5, -2): Let's look at a quick example algebraically if you're not clear yet: Example 1: Find the point halfway between \((0,3)\) and \((4,7)\): Remember the midpoint formula: $$ (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}) $$ Plug in the appropriate values:
