In the analysis of potassium ions in a water sample, the following signals (yi) were read from the flame photometer for K+ ion concentrations (xi). Accordingly, calculate the line equation of the calibration graph, the std deviation of the slope, the std deviation of the point where the line intersects the y-axis, and the regression coefficient (R2) of the calibration graph. (xi and yi in the attachment.)
