First find their values
4x-2y=2 can be divided by 2
=2x-y=1, which is the same as the given first equation. Then set up a table of values which can help you graph.
Lets say:
x=-2,-1,0,1,2
Substitute each x value to y
2(-2)-y=1
-4-y=1
-y=5
y=-5
2(-1)-y=1
-2-y=1
-y=3
y=-3
2(0)-y=1
-y=1
y=-1
2(1)-y=1
2-y=1
-y=-1
y=1
2(2)-y=1
4-y=1
-y=-3
y=3
Now, make the coordinates
(-2,-5),(-1,-3),(0,-1),(1,1)(2,3)
Now graph this, remember: this forms a straight line because its linear. Just connect the points and that's the graph
Hope this helps =)
