The rate at which the ice changes is -3/8 lb per hr

<h3>What is the rate the ice changes?</h3>

The given parameters are:

Changes =1 3/4 lb to 1/4 lb

Time = 1/4 hr.

The rate the ice changes is calculated as:

Rate = Change/Time

So, we have

Rate = (1/4 lb - 1 3/4 lb)/(1/4 hr)

Evaluate the difference

Rate = (-1 1/2 lb)/(1/4 hr)

Evaluate the quotient

Rate = -3/8 lb per hr

Hence, the rate at which the ice changes is -3/8 lb per hr

Find the slope of the line.

Morgarella [4.7K]

The slope:

$m=\dfrac{\Delta y}{\Delta x}$

Look at the picture.

6 units down → -6

2 units right → 2

$m=\dfrac{-6}{2}=-3$

<h3>Answer: Slope = m = -3</h3>
