Find the midpoint of the segment with the given endpoints. (-1,3) and (-3,-9)

( -2,-3) is the midpoint

Step-by-step explanation:

To find the x coordinates of the midpoint, add the x coordinates of the endpoints and divide by 2

( -1+-3)/2 = -4/2 =-2

To find the y coordinates of the midpoint, add the y coordinates of the endpoints and divide by 2

( 3+-9)/2 = -6/2 =-3

( -2,-3) is the midpoint

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
