Estimating a Sum Which problem shows estimation to the tenths place correctly?
o
1.35 +0.42
243-236
431-0.06
2.34 +0.67
v
230+ 0.70 = 3.00
1.30-0.40 = 1.70
240=230=470
4.4-0.1=4.5

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

it is only things thain can be deafeated

step-by-step explanation:

answer: the answer is   graph (a)
