Question

The sum of two numbers is 75 and their difference is -25

Answer 1

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
