Answer:

m = -32

Step-by-step explanation:

Let x = days and y = box of cookies

So, we have:

(x_1,y_1) = (0,228) -- When she started

(x_2,y_2) = (4,100) --- After 4 days

Required

Determine the slope

The slope (m) is calculated using:

m = \frac{y_2 - y_1}{x_2 - x_1}

m = \frac{100 - 228}{4 - 0}

m = \frac{-128}{4}

m = -32

<em>The slope is -32</em>
