To find the \( r \)-value, or the correlation coefficient, for the linear equation \( y = -2x + 5 \), we can analyze the relationship between \( x \) and \( y \).
However, correlation coefficients are generally calculated from data points, not from an equation itself. The correlation coefficient \( r \) ranges from -1 to 1:
- \( r = 1 \) indicates a perfect positive linear relationship.
- \( r = -1 \) indicates a perfect negative linear relationship.
- \( r = 0 \) indicates no linear relationship.
Since the equation \( y = -2x + 5 \) represents a perfect linear relationship, the correlation coefficient \( r \) would be \( -1 \).
If you had data points that fit this linear equation and were using a calculator or statistical software, you would input the data points to compute \( r \). If you can provide data points, I can help you further. Otherwise, based on the given linear relationship, the \( r \)-value is \( -1 \).
