Question

Show graphically the equation of x+2y=8 and x+2y=15

Answer 1

equation is, x+2y=8
put x=0
0+2y=8
2y=8
y=4
therefore it's point A(0,4)
and now y=0
x+2×0= 8
x=8
therefore it's points B (8,0)

equation second
x+2y= 15
put x=1
1+2y= 15
2y=15-1
2y=14
y=7
points A(1,7)
put y=0
x=15
points B (15,0)
