shtirl [24]

Answer:

X = -3

Y = -5

Step-by-step explanation:

Find the midpoint of the segment from point a (6,3) to point B (8,1)
velikii [3]

Answer: M=(7,2)

Step-by-step explanation:

You need to use the following formula:

 M=(\frac{x_A+x_B}{2},\frac{y_A+y_B}{2})

Given the points A(6,3) and B(8,1), you can identify that:

x_A=6\\x_B=8\\y_A=3\\y_B=1

Now, you can substitute these values into the formula M=(\frac{x_A+x_B}{2},\frac{y_A+y_B}{2}).

Therefore, you get this result:

M=(\frac{6+8}{2},\frac{3+1}{2})

M=(7,2)
