Answer 1

See plot the lines on a graph sheet.

x + y = 2

Take a random value of x and then see how much y is then.
Do it for 2 points so that it can be plotted on the graph.
Points can be: (1,1) , (2,0) , (0,2) [Because then only x+y = 2]

Then do it for this too

x = 1

x = 0*y = 1
y can be ANYTHING
x has to be 1
Points can be (1,0) , (1,2) , (1,3)

Getting mt? :)

Answer 2

one sec im reding might take a while do understand

Answer 3

EXTRA INFO:

When x = constant [Like here it is, x=1]

The line formed is parallel to the y axis. Because the x value never changes then!

Like in this diagram.

Answer 4

you can go on to a diff quetion im still reding

Answer 5

then none of them work

Answer 6

See the last one! :D
