Question

Draw a graph of equation 2x+y=5 and x+y=3

Answer 1

Step-by-step explanation:

2x+y=5

y= 5-2x...........(1)

Let x=0, then y=5-2(0)=5-0=5

x=1, then y=5-2(1)=5-2=3

x=-1, then y=5-2(-1)=5+2=7

x=2, then y=5-2(2)=5-4=1

(0,5) (1,3) (-1,7) and (2,1) by using these coordinates locate the points and join the points by using scale.

and x+y=3

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

Let x=0, then y=3-0=3

x=1, then y=3-1=2

x=-1, then y=3-(-1)=3+1=4

x=2, then y=3-2=1

(0,0) (1,2) (-1,4) and (2,1)

by using these coordinates locate the points and join the points by using scale.
