Question

if the mid point of (-4,a) and (2,8) is (-1,5). then what is a ?
pls give step by step explanation​

Answer 1

mid point =(-1,5)

$5 = \frac{a + 8}{2} \\ 10 = a + 8 \\ a = 10 - 8 \\ a = 2$

to find the mid point just add the two values and divide it by 2.

by this we can find other values too.
