Answer:
y = 10
Step-by-step explanation:
-7x + 3y = 30
(-7 x 0) + 3y = 30
0 + 3y = 30
3y = 30
y = 10
The critical points of the function graphed are given as follows:
<h3>What are the critical points of a function?</h3>
The critical points of a function are the values of x for which:

In a graph, they are turning points, and are classified as follows:
- Local maximum, if the functions changes from increasing to decreasing.
- Local minimum, if the functions changes from decreasing to increasing.
Looking at the graph, the turning points are approximately:
