Answer:
x=1, y=-7
Step-by-step explanation:
y=-9x+2 -->y+9x=2
y=-3x-4 -->y+3x=-4
subtract the equations
6x=6
x=1
substitute
y=-9+2
y=-7

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:
