Determining the equation of a straight line
WebJun 11, 2024 · Figure 5.4.1 shows the data in Table 5.4.1 plotted as a normal calibration curve. Although the data certainly appear to fall along a straight line, the actual calibration curve is not intuitively obvious. The process of determining the best equation for the calibration curve is called linear regression. WebTo find the equation of a line when given two points on the line, we first find the slope and then find the y-intercept. The slope is the ratio of the change in the y-value over the …
