B)As the X variable increases,the Y variable increases in a linear way.
C)The scatter diagram shows a linear pattern that is going uphill.
D)All of these choices are true.

All three options are true indicators of a positive linear relationship between two interval variables. A scatter plot where most points fall close to a straight line with a positive slope, as the X variable increases, the Y variable also increases in a linear way, and the pattern on the scatter plot is linear and going uphill are all indications of a positive linear relationship. Therefore, we can say that all the choices are correct.
