# If the coefficient of determination is a positive value, then what kind of slope must the regression equation have?

##### 1 Answer

The regression equation must have a positive slope.

#### Explanation:

The coefficient of determination, which can be any value from -1 to 1, denotes the strength and direction of the relationship between the x-value and the y-value.

Coefficients of determination near 0 indicate a weak or nonexistent relationship.

Positive coefficients of determination indicate that there is a positive relationship- y generally increases with x.

Negative coefficients of determination indicate that there is a negative relationship- y generally decreases as x increases.

Positive slopes indicate that there is a positive relationship- y increases with x.

Negative coefficients of determination indicate that there is a negative relationship- y decreases as x increases.
