Question: how to find the slope of a scatter plot?
Answer: Use the formula for the slope of a line, m = (y2 - y1)/(x2 - x1), to find the slope. By plugging in the point values, m = (0.5 - 1.25)/(0 - 0.5) = 1.5. So with the y-intercept and the slope, the linear regression equation can be written as y = 1.5x + 0.5.
