Answer:
Linear decreasing
Explanation:
We are given that a graph
We have to find the type of graph.
Increasing function: If

Then ,

Decreasing function:If

Then,

The given graph is not exponential graph because exponential graph is type of curve.
But given graph is line graph.
The equation of line

The equation of line is linear equation.
When x increasing then value of function decreasing with increasing value of x.
Hence, the graph is linear decreasing.
