heya
here is ur answer
➡ formula :-y2-y1/x2-x1
here :-
x1=0
X2= 8
y1= -4
y2=0
⭐ as it is passing from the mid point , divide it by 2
(0,-4)/2,(8,0)/2
so (-2),(4)
hence the slope is -2/4 = -1/2

AaanyaKandwal:
But sis the answer is -1/2
if the value of y1 is 4 then the answer will be -1/2
OK thnxx
it is wrong , plz edit
i can't edit my answer because it is reported

Hi ,
Mid point of P( 0, - 4 ) and B( 8, 0)
= [ ( 0 + 8 )/2 , ( -4 + 0 ) /2 ]
= ( 4 , - 2 )
Now ,
Slope of a line passing through origin
and point ( 4 , - 2 )
slope ( m ) = y/x
m = -2/4
m = -1/2
I hope this helps you.

I have a doubt
y did u divided it by 2
mid point of joining the points ( x1 , y1 ) and ( x2 , y2 ) = [ ( x1+x2)/2 , ( y1 + y2 ) /2 ]
ok ,thnq
we have find out the slope of a line which passes through the mid point of PB and the origin
is it clear
yes
thanks alot
