Answer:

1,7.5

Step-by-step explanation:

use the equation (x(1) + x(2) ) /2, (y (1) + y (2) ) /2

x(1) is x sub one or -4 since it is the first x value we are given

x(2) is x sub two or 6 since its the second x value we are given

-4+6=2

2 divided by 2 is one


y(1) is y sub one or 8 since it's the first y value we are given

y(2) is y sub two or 7 since it's the second y value we are given

8+7=15

15/2 is 7.5

this gives you x,y or 1,7.5

Answer:

(1, 7.5)

Step-by-step explanation:

As we go from A to B, x increases by 10.  Half that is 5.  Adding 5 to the x-coordinate of A, we get the x-coordinate of the midpoint:  it's 1.

Alternatively, find the mean of the x-coordinates of A and B:  (-4+6)/2 = 1

As we go from A to B, y decreases by 1.  Half of that is 1/2.    Subtract 1/2 from the y-coordinate of A:  8 - 1/2 = 7 1/2.  

Thus, the midpoint is (1, 7.5).
