Answer:
m=4.9
Step-by-step explanation:
The midpoint between points a and b, if [tex]a\leq b[/tex], is located half the length of the interval [tex][a,b][/tex]. The length of the interval is found with the formula b-a.
Therefore, the midpoint of the line segment joining a and b is [tex]\frac{b-a}{2}[/tex].
In this case. a=-5.5 and b=4.3.
Then the midpoint (m) of the line segment joining the points R(4.3) and S(-5.5) is [tex]m=\frac{4.3-(-5.5)}{2}=\frac{9.8}{2}=4.9[/tex]
