They can but the two are related when both are zero. Otherwise, it is like your weight and height having the same value (in some units).

What is the difference between positve and negative correlation?
Positive correlation has a positive slope and negative correlation has a negative slope.
How can you tell from a scatter plot wheather two variables have a positive correlation a negative correlation or no correlation?
Positive correlation = the slope of the scattered dots will rise from left to right (positive slope) Negative correlation = the slope of the scattered dots will fall from left to right (negative slope) No correlation = no real visible slope, the dots are too scattered to tell.
What is the name of the correlation in maths with a slope?
In mathematics, the correlation associated with a slope is often referred to as the "linear correlation." This relationship is typically represented by a linear equation, where the slope indicates the rate of change between two variables. A positive slope indicates a direct relationship, while a negative slope denotes an inverse relationship. The strength and direction of this correlation can be quantified using the Pearson correlation coefficient.
A positive value for a correlation indicates?
A positive value for a correlation indicates a positive correlation; e.g. it has a positive slope.
Is the slope of a line positive when doing linear regression if the correlation coefficient is negative?
No, the slope of a line in linear regression cannot be positive if the correlation coefficient is negative. The correlation coefficient measures the strength and direction of a linear relationship between two variables; a negative value indicates that as one variable increases, the other decreases. Consequently, a negative correlation will result in a negative slope for the regression line.

What can you say about the relationship between a correlation r and the slope b of the least squares line form of data?
You can say that the correlation is positive if and only if the slope is positive. The correlation is zero if and only if the slope is zero. And the correlation is negative if and only if the slope is negative. On the other hand, slope does change when your measurement units change, while correlation does not change. (For example, the correlation between height in inches and weight in pounds will be the same as the correlation between height in centimeters and weight in kilograms, as long as both sets of measurements were taken on the same observations.)
A positive value for a correlation indicates?
A positive value for a correlation indicates a positive correlation; e.g. it has a positive slope.
What type of correlation is a straight line with no slope?
The straight line with no slope is a point
What negative correlation indicate?
the negative sign on correlation just means that the slope of the Least Squares Regression Line is negative.
Is the slope of a line positive when doing linear regression if the correlation coefficient is negative?
No, the slope of a line in linear regression cannot be positive if the correlation coefficient is negative. The correlation coefficient measures the strength and direction of a linear relationship between two variables; a negative value indicates that as one variable increases, the other decreases. Consequently, a negative correlation will result in a negative slope for the regression line.
Which is typically steeper a positive or negative slope?
There's absolutely no connection or correlation whatsoever between the steepness and the direction of a slope.
What is the correlation if x values are equal to the y values?
Positive Correlation
Can a correlation equal to 3?
A correlation coefficient cannot exceed 1.
What type of correlation do you have when are is equal to one?
A correlation coefficient of 1 (r=1) is a perfect positive correlation.
