Question

Graph x+y=8 and x-y=4

Answer 1

Answer:

See attached photo for graphs.  

Step-by-step explanation:

The first step is to solve each equation for y, then graph using slop-intecept form...

x + y = 8

 

  y = -x + 8         (subtract x from both sides)

x - y = 4

   -y = -x + 4     (subtract x from both sides)

       y = x - 4       (divide both sides by -1)
