Question

Draw the graphs of the following pair of equations
(1) 2x+y=2
(2) 2x+y=8

Answer 1

Answer:

Step-by-step explanation:

1) if x=0

2(0)+y=2

y=2

if x=1

2(1)+y=2

2+y=2

y=2-2

y=0

if x=2

2(2)+y=2

4+y=2

y=-2

2)

if y=0

2x+0=8

x=8/2

x=4

if y=1

2x+1=8

2x=8-1

2x=7

x=7/2

if y=2

2x+2=8

2x=8-2

2x=6

x=6/2

x=3
