Which associations best describe the scatter plot? linear, negative, nonlinear, or positive association?

We can see from the graph that the points form a linear association (we know this beacuse it looks like a straight line, just like that)

Also, it is a negative association because the line has negative gradient or slope (say the equation of the line is y = mx +b,  then m<0). This means that as one variable increases the other decreases.
