Answer 2

Answer:

b) $\frac{x}{a} +\frac{y}{b} =1$

Step-by-step explanation:

given, P(x,y) lies on line joining A(a,0) and B(0,b)

line formed by two points = (x-x₁)(y₂-y₁)/(x₂-x₁)=y-y₁

A(a,0) =(x₁,y₁)

B(0,b)=(x₂,y₂)

P(x,y)=(x,y)

sub in formula

x-a(b-0)/(0-a)=y-0

x-a(b)/-a=y

xb-ab=-ya

xb+ya=ab

$\frac{xb+ya}{ab}$=1

$\frac{x}{a} +\frac{y}{b} =1$
