If(1,p/3)is the mid point of the line segment joining the points (2,0)and (0,2/9),then show that the line 5x+3y+2=0passes through the point (-1,3p)??. Plz answer it fast for model examzzzz anyone who answers will be marked as BRAINLIEST answer!

Let a(1,p/3) be midpoint of the join of BC with b(2,0) and c(0,2/9) then
By section formulae,p/3 =2/9/2
P/3 = 1/9. P=1\3
Substuting p=1/3 in d(-1,3p)
So the point become d(-1,1)
If 5x+3y+2=0 passes through it x=-1 y=1
On substuting it in 5x+3y+2=0
It becomes -5+3+2=0. This satisfies the equation thus this line passese through d(-1,3p)
By section formulae,p/3 =2/9/2
P/3 = 1/9. P=1\3
Substuting p=1/3 in d(-1,3p)
So the point become d(-1,1)

On substuting it in 5x+3y+2=0

cutechocolate:
p/3 is not there in question it is p*3
