Question

if x+3y=4 and 4x +2y = 8 then represent these lines graphically​

Answer 1

Given :  x  + 3y  = 4

4x + 2y  = 8  

To Find :  represent these lines graphically​

Solution:

x  + 3y  = 4

x = 1   => y  = 1

x = 4   => y = 0

plot points ( 1 , 1) and ( 4 , 0)  and draw a line passing through points

4x + 2y  = 8  

x = 0  => y = 4

x = 2  => y = 0

Plot points  ( 0 , 4) and ( 2 , 0)   and draw a line passing through points

both  lines  intersects at (1.6 , 0.8)
