Explanation:

Step1: Locate x - value on graph

Locate x = 1 on the x - axis (representing cups of oats).

Step2: Find corresponding y - value

Move vertically from x = 1 until intersecting the line. Then move horizontally to find the y - value (representing grams of almonds). By observing the graph, when x = 1, y = 50. So k = 50.

Step3: Explain the meaning

The point (1, 50) means that when there is 1 cup of oats in the granola mix, there are 50 grams of almonds.

Answer:

k = 50. The meaning is that there are 50 grams of almonds when there is 1 cup of oats in the granola mix.
