Answer:

Part A:

Slope-intercept form   ⇒ y = mx +

Where:

m = slope  ⇒  (y₂-y₁) / (x₂-x₁)

b is the y-intercept = 44

Find the slope:

m = (0-44) / (8-0)

m = -44/8

m = -11/2

Equation in slope-intercept form:

y = -11x/2  + 44

Part B:  

x=0  and y=44

Originally, Jake had 44 cups of butter.

Part C:

Batch of cookies: x = 1

Substitute to the equation:

y = -11x/2 + 44

y = -11(1)/2 + 88/2

y = -11/ + 88/2

y = 77/2 or 38 ¹/₂

Jake used 38 ¹/₂ cups of butter for the first batch of chocolate chip cookies.
