Question

find the equation of line joining the origin to the point of intersection of 4x+3y=8 and x+y=1

Answer 1

Answer:

Step-by-step explanation:

origin=(0,0)

intersection of 4x+3y=8 and x+y=1 is:

4x+3y=8    ..........................(1)

(x+y=1)*3

3x+3y=3........................(2)

Solving equation (1) and (2)

4x+3y=8

3x+3y=3

-   -      -

x=5

3x+3y=3

3*5+3y=3

3y= -12

y= -4

Let the point of intersection be P

p(5,-4)

origin(0,0)

m(slope)= y-y1/x-x1

              = 0-(-4)/0-5

              =4/-5

               =-4/5

m=y-y1/x-x1

-4/5=y+4/ x-5

-4*(x-5)=5(y+4)

-4x+20=5y+20

5y+4x=0
