Given the variables y and x
If these variables have a negative linear correlation, the slope of the graphic (correlation coefficient) will be negative:
ρ<0
If the variables x and y have a positive linear correlation, the slope of the graphic will be positive:
ρ>0
If the variables x and y have are not correlated, the slope of the graphic will be zero:
ρ=0
For the given graph, the variable y increases together with the variable x, the slope of the graph is positive.
So you can conclude that there is a positive correlation between these two variables.
