When two variables are positively related, the graph of the relationship?

When two variables are positively related, the graph of the relationship is an upward-sloping curve. This means that as the value of one variable increases, the value of the other variable also increases. For example, if we consider the relationship between the amount of money spent on advertising and the sales of a product, we would expect to see an upward-sloping curve. As the amount spent on advertising increases, we would expect to see an increase in sales. Conversely, when two variables are negatively related, the graph of the relationship is a downward-sloping curve. This means that as the value of one variable increases, the value of the other variable decreases. A straight line on a graph usually represents a constant relationship between two variables, where the value of one variable remains constant as the value of the other variable changes. Therefore, for a positive relationship, the graph is an upward-sloping curve, not a downward-sloping curve or a straight line.
