Final Answer : y=23x+2
Steps:
1) Slope of line,m = 23
Since, P divides A (-2,3) and B(3,-4) in the ratio
2:3 internally.
By Section Formula,
P(x,y) =
3) Slope of line : m = 23
Point on line, P(x,y) = (0,2)
Now,
Equation of line :
Slope Form :
(y-2)=23(x-0)
=> y = 23x + 2
Steps:
1) Slope of line,m = 23
Since, P divides A (-2,3) and B(3,-4) in the ratio
2:3 internally.
By Section Formula,
P(x,y) =
3) Slope of line : m = 23
Point on line, P(x,y) = (0,2)
Now,
Equation of line :
Slope Form :
(y-2)=23(x-0)
=> y = 23x + 2

Solution:-
given by:-
we have:-
》The point P divides the line segment joining A(-2,6) and B(3,-4) in the ratio 2 : 3
》Slope of the line = 3/2
》= (L x₂ + m x₁)/(L + m) , (L y₂ + m y₁)/(L + m)
》 = [2(3) + 3 (-2)]/(2 + 3) , [2(-4) + 3 (6)]/(2 + 3)
》 = [6 - 6]/5 , [-8 + 18]/5
》 = 0/5 , 10/5
》 = (0 , 2)
Equation of the line:
by formula:-
》(y - y₁) = m (x - x₁)
》(y - 2) = (3/2) (x - 0)
》2(y - 2) = 3 x
》2y - 4 = 3x
》3x - 2y + 4 = 0
equation of the line ( 3x-2y+4=0) ans
