Ответ:
The coordinates of the midpoint of LB are (1, 3.5)
Step-by-step explanation:
The rule of the midpoint of a segment its endpoints are (x1, y1) and (x2, y2) is![M=(\frac{x1+x2}{2},\frac{y1+y2}{2})](/tpl/images/0819/7876/ea449.png)
Let us use this rule to solve the question
∵ M is the midpoint of segment LB
∵ The coordinates of point L are (8, 5)
∴ x1 = 8 and y1 = 5
∵ The coordinates of point B are (-6, 2)
∴ x2 = -6 and y2 = 2
→ Substitute these values in the rule of the mid point above
∵![M=(\frac{8+-6}{2},\frac{5+2}{2})](/tpl/images/0819/7876/437dc.png)
→ Remember (+)(-) = (-)
∴![M=(\frac{8-6}{2},\frac{7}{2})](/tpl/images/0819/7876/d5d94.png)
∴![M=(\frac{2}{2},\frac{7}{2})](/tpl/images/0819/7876/ab0ce.png)
∴ M = (1, 3.5)
∴ The coordinates of the midpoint of LB are (1, 3.5)
