so,fo example i have this results (PROC REG). now i have to show regresson equaton (which is y=0.33096x+1028.57177) on my graph. Moreover, i need find "y" for different x?

Thank you.

**Goal: Displaying Regression Equations in Fit Plots and use this equation to find "y" for certain x**

You didn't say what version of SAS you are using, but here how to use PROC SGPLOT to display the slope and intercept of a regression line.

If you want to get REALLY fancy, you can use string concatenation to construct an "equation" and display the equation.

There are many ways to score a regression model. See examples and explanations in this article: Techniques for scoring a regression model in SAS

How are you making your graph? Where do you want to include equation?

Look at score and/or proc score to calculate predictions.

If you are plotting using SGPLOT, use INSET statement to show the equation. If you want the predicted y values for your data x values, then use an OUTPUT statement in PROC REG. You can also create the SAS code for the calculation of predicted values in a separate data step with the CODE statement in PROC REG.
