Answer:

y = -5x + 1

Step-by-step explanation:

Given:

The slope m = -5 and point (2, -9)

Use point slope form:

y - y₁ = m(x - x₁), where (x₁, y₁) is the given point

So the equation is:

y - (-9) = -5(x - 2)
y + 9 = -5x + 10
y = -5x + 1

So, the actual length of the cookie is $18[1-\frac{1}{4} ]=18 \times \frac{3}{4}=13.5$ inches.

If all the four of them get the same amount of the giant cookie then each of them will get $\frac{13.5}{4} = 3.375$ inches of cookie. (Answer)
