the question wants to find the area of the triangle formed by this three point and express it in terms of k.

thus,

area of the triangle formed = **-11-4k**

since area has to be positive, so i put modulus? = **|-11-k|** in order to get positive answer.

but |m|= +-m. *true?*

so, what is answer the area of the triangle? if i did not use modulus, area of the triangle might be negative. but if i use modulus,|m|= +-m.

confused! (Wondering)
