Question

X+2y=1
X-2y=-7
Express graphically

Answer 1

Step-by-step explanation:

in first question

take y=1

x+2(1)=1

x=1-2

x=-1

similarly take y=2

x+2(2)=1

x=1-4

x=-3

now take y =3

x+2(3)=1

x=1-6

x=-5

now take y =4

x+2(4)=1

x=1-8

x=-7

now in another question

x-2y=-7

take y =1

then take y =2

then take y =3

then take y =4

and then draw the graph by using both the questions

hope u got it
