Help with graphing calculator- getting back to regular graphing mode?

Question

I was using the STAT portion of the calculator in order to graph a point by point linear regression, and would now like to go back to the regular mode so that I am able to graph functions typed in the y= section. Currently, when I press graph, it says ERR: INVALID DIM

Any help would be appreciated and 10 points to the best answer
