Answer 1

To find the correlation coefficient \( r \) for the linear equation \( y = 43x - 4 \), we should consider the properties of linear equations. The equation represents a perfect linear relationship, as it can be described in the form \( y = mx + b \), where \( m \) is the slope and \( b \) is the y-intercept.

In this case, since the slope (43) is not zero, the correlation coefficient \( r \) for this perfectly linear relationship would be 1.00.

Thus, the correct response is:

1.00
