Bob's pancake house charges $3 per plate of pancakes and then $1 for a drink, as shown by the graph. What is the slope of the line graphed and what does it represent?

• slope = $\frac{1}{3}$ ; represents cost per plate

• slope = $\frac{1}{3}$ ; represents cost per plate plus a drink

• slope = 3 ; represents cost per plate

• slope = 3 ; represents cost per plate plus a drink
