Question

Hwan decides to lose weight before the wrestling season begins. He weighs 148 pounds now and loses one pound per week for six weeks. Let y represent Hwan’s weight and let x represent the time in weeks. What is the slope of the line?

The y intercept is 148

Answer 1

-1lb/6wk = -1/6 lb/wk

that is the slope

y = 148 - x/6

Answer 2

I dont get it

Answer 3

Same question as this.

why are you repeating it ??

btw, it said he loses one pound per week for 6 weeks
so the equation could be written
y = -x + 148 , x ≤ 6

"the for 6 weeks" simply limits the domain of the function so the results stay within logical limitations.
