Answer: a= -6
Step-by-step explanation:
use midpoint formula..
P(x,y) = {(x₁+x₂)/2 , (y₁+y₂)/2}
P(a/2 , 2) = {(-5+(-1)/2 , (4+0)/2}
P(a/2 , 2) =(-3,2)
a/2 = -3
a=2×-3
∴a=-6

Answer: -6
Step-by-step explanation:
Given that p is the mid point of Q(-5,4) and R(-1,0) ,
x coordinate of P = x coordinate of Q + x coordinate of R /2
a/2 = (-5) + (-1)/2
a= -6
