The formal term to describe a straight line graph is linear, whether or not it goes through the origin, and the relationship between the two variables is called a linear relationship. Similarly, the relationship shown by a curved graph is called non-linear.

One may also ask, what is a negative relationship on a graph? A negative relationship is one in which two variables move in opposite directions. The slope of a curve describing a negative relationship is always negative. A curve with a negative slope is always downward sloping.

Herein, what does a positive correlation look like on a graph?

If the data points make a straight line going from the origin out to high x- and y-values, then the variables are said to have a positive correlation . If the line goes from a high-value on the y-axis down to a high-value on the x-axis, the variables have a negative correlation .

What is a positive relationship between two variables?

A positive correlation is a relationship between two variables where if one variable increases, the other one also increases. A positive correlation also exists in one decreases and the other also decreases.
