Answer : 2.5
Solution:
To find the halfway number it means that you need to find the middle most value using the formula
Mid value = (X + Y) / 2
So in this case it would be,
Mid value =  (-15 + 20 ) / 2
Mid Value = ( 5 ) / 2 
Mid Value = 2.5 answer 
Hope this helps in understanding the question! :)
Note : do not forget the negative sign as it will change the answer and may cost you marks!

<span>points (6,10)
</span>y = -x
x + y = 0
distance = lax1 + by1 + cl/√(a^2 + b^2)
 = l1(6) + 1(10) + 0l/√(1^2 + 1^2)
 = l6 + 10 + 0l/√(1 + 1)
 = l16l/√2
 = 16/√2
 = 8 .2/√2
 = 8 . √2.√2/√2
= 8√2
