Answer 1

Answer: C. 5.75 calories per gram

Step-by-step explanation:

Given: A line on a graph shows a proportional relationship between the amount of almonds, x, in grams and the total calories y.

From the given point  (50, 287.5)

Calories in 50 grams of almonds=287.5 calories

Thus, Calories in 50 grams of almonds=$\frac{287.5}{50}=5.75\ calories$

Hence, the unit rate for the number of calories per gram of almonds =5.75 calories per gram

Answer 2

C. 5.75 calories per gram

Edit: 287.5÷50=5.75
402.5÷70=5.75
