Find the midpoint of (-7,-2) and (1,7)

(-3 ,2.5)

Step-by-step explanation:

midpoint formula is

 x1+x2        y1+y2

(___    ,       )

  2                   2

(-7,-2)     -7 is x1 i.e the first x point and -2 is y1 1st y point

(1,7)        1 is x2 i.e the second x point and 7 is y2 the second y point

now we use input the numbers to the formula

-7+1         -2+7          

(  , )

2             2

we the signs are different you subtract and use sign of greater number

-6          5

__ ,     ___

2           2

Now you divide

and here is the ordered pair for midpoint.

(-3 ,2.5)
