I have a set of data as follows:

1....... 58.82±3.23

10....... 62.5±7.90

50....... 87.23±2.33

100....... 110.29±10.33

200....... 84.56±8.67

I have the linear regression equation for the above data, which is y=50.2530+0.2822x and correlation coefficient (r) as 0.5858. But the problem is that I don;t know how to reach this equation and r from the above mentioned data.

Any help will be highly appreciated.
