When x<4, the graph is decreasing.
When x>4, the graph is increasing.
Vertex (4, -3)
Answer:
undefined
Step-by-step explanation:
The slope formula tells you the slope is ...
m = (y2 -y1)/(x2 -x1)
Fill in the point coordinates, we find the slope to be ...
m = (6 -9)/(-5 -(-5)) = -3/0
This slope is undefined.
___
It means the line is a vertical line. The constant must match the x-coordinates of the points:
x = -5 . . . . the line through the given points
