If P(-3,P) lies on 7x+5y=-14,then it is the zero of given equation.
Therefore, substituting -3,P in the equation,7(-3)+5(P)=-14.
-21+5p=-14.
5p = -14+21=7.
p=7/5.
Therefore, substituting -3,P in the equation,7(-3)+5(P)=-14.
-21+5p=-14.
5p = -14+21=7.
p=7/5.

if point lies on line then will also satisfy it
so put the point in line we get
7 *-3 + 5p+14=0
-21+5p +14 = 0
5p = 7
p = 7/5
so put the point in line we get
7 *-3 + 5p+14=0
-21+5p +14 = 0
5p = 7
p = 7/5
