Hi, I'm having trouble calculating the strength of R-squared and a regression equation. I'm not sure how to do so. Can you tell me the equations to use and how to determine which numbers to use in said equations? These are my calculated statistics:
| Regression Statistics | |
| Multiple R | 0.9304952 |
| R Square | 0.865821318 |
| Adjusted R Square | 0.863025929 |
| Standard Error | 64537.12352 |
| Observations | 50 |

| df | SS | MS | F | Significance F | |
| Regression | 1 | 1.29E+12 | 1.29E+12 | 309.731938 | 1.42368E-22 |
| Residual | 48 | 2E+11 | 4.17E+09 | ||
| Total | 49 | 1.49E+12 |
| Coefficients | Standard Error | t Stat | P-value | Lower 95% | Upper 95% | Lower 95.0% | Upper 95.0% | |

And these are my graphs. One contains the line of best fit equation, and one contains the regression equation.
