Final answer:
The regression equation Y Ì = .25X + 12 represents a linear relationship between the X and Y variables. The line would have a positive slope of .25 and cross the Y-axis at 12.
Step-by-step explanation:
The regression equation Y Ì = .25X + 12 represents a linear relationship between the X and Y variables. The shape of a linear equation is a straight line. In this case, the line would have a positive slope of .25 and would cross the Y-axis at the y-intercept, which is 12. Therefore, the correct answer is Linear, at Y=12.
