Question

X+ y = 8
x- y = 2
How do I graph this

Answer 1

Subtract y from first one

Add y to second one so:

x =8-y

x =2+y

For the first one, find 8 on the Y axis and mark a point. Then go down right and down one. Mark another point. Connect the dots.

For the second one, find 2 on the Y axis and mark a point. Go up and right and up one.

Mark another point. Connect the points.

Hope this helps
