Sarah and jessica are sister's. sarah's height is s inches and jessica height is j inches. their father wants to know how many inches separate the two . write and equation for this difference in such a way that the result will always be positive no matter which is taller

Let d be the difference between the heights of Sarah and Jessica.

If Sarah is taller, then d = s - j

If Jessica is taller, then d = j - s

So, d = s - j or d = - (s - j)

Hence, d = |s - j|, the absolute value equation which always gives positive result.

it has the same slope and a different y-intercept

hope this : )
