Answer:

  • y = -x + 75
  • y = x + 25

Step-by-step explanation:

We know that:

  • x + y = 75
  • x - y = -25

Solution:

  • x + y = 75
  • => y = -x + 75

Now, let's re-organize the second equation into slope intercept form.

  • x - y = -25
  • => x + 25 = y
  • => y = x + 25

Hence, the two equations in slope intercept form are:

  • y = -x + 75
  • y = x + 25
