Hi Lyn,
E1) x - y = 5
E2) x + y = 3
:
For E1) let x=0 and solve for y:
0-y=5
-y=5
-1(-y)=-1(5)
y=-5 Plot (0,-5)
Now let y=0 and solve for x:
x-0=5
x=5 Plot (5,0)
Connect the points and you have this line:

For E2) let x=0 and solve for y:
0+y=3
y=3 Plot (0,3)
Now let y=0 and solve for x:
x+0=3
x=3 Plot (3,0)
Connect the points and you have a second line:

They intersect at: (4,-1)
Happy Calculating, Lyn!!!
