Question

if (2,3)and (4,0)lie on the graph of the equation ax+by=1find the value of a and b​

Answer 1

Answer:

Step-by-step explanation:

points A(2,3),B(4,0)lie on line ax+by=1

so points A,B must satisfy the eqn

so

2a+3b=1....(1)

4a + (0)×b=1

a=1/4

put in(1)

2×1/4 + 3b=1

1/2+3b=1

3b=1/2

b=1/6

a=1/4,b=1/6

Answer 2

a=1/4 b = -7/3

Step-by-step explanation:

the given points must satisfy the given equation as the points lie on the line of given equation

for point (4,0) y=0 ,x=4

4a +0= 1

a=1/4

and now for point (2,3)

x=2 ,y=3

4*2 + 3b=1

b= -7/3
