the point on the line that corresponds to a savings of $30 is about. this means that if pounds of birdseed are purchased, aisha will save $30

Explanation:

Step1: Identify the relationship on the graph

The graph shows a linear - relationship between pounds of birdseed purchased ($x$) and savings ($y$).

Step2: Find the point for $y = 30$

We look at the $y$-axis for the value of $30$ (savings) and then find the corresponding $x$ - value (pounds of birdseed) on the line. By visually inspecting the graph, when $y = 30$, the $x$ - value is approximately 8.

Answer:

8
