Question 74527
equation is y=2x+4............(1)
( , 0) that means y=0 given now put y=0 in the equn .(1)
we have 0=2x+4
 or    -2x=4
  or   -x= 4/2
  or    -x = 2
so x = -2
ans is (-2,0)
(1/2, ) that means x=1/2
 so y= 2(1/2) +4
     =  2/2 +4
     =  1 +4
     = 5
 ans is ( 1/2 ,5)
(0,  )  that means x=0
   so y = 2*0 +4
    or y = 4
ans is ( 0,4)
(-1/2 , ) here x= -1/2
so y = 2(-1/2) + 4
     =-2/2 +4
     = -1 + 4
     =3
ans ( -1/2,3)
