The fasting glucose rate (fpg) and the HbA level of 20 people with diabetes were collected. The results of a simple linear regression are shown below. Intercept: 64.5, slope: 8.1, standard deviation of the independent variable (HbA): 1.2, standard deviation of the dependent variable (fpg): 12.3. Plot the least-squares regression line

I understand the regression line would be y=8.1x + 64.5, but how can that be plotted on a graph/spss software with no data
