How do I find the gradient of a best fit line?

Using autograph I created a best fit line for a scatter graph. How would I work out the gradient of the line y = 36.9x - 7.37?How do I find the gradient of a best fit line?

The gradient of a line is the number before the x





So the gradient of your line is 36.9
