Final answer:
To find the equation of a secant line, determine two points on the curve and calculate their coordinates. Use the slope formula to find the slope, and then write the equation using the slope-intercept form.
Step-by-step explanation:
The equation of a secant line can be found using the slope formula. The slope of a secant line is equal to the change in y-coordinates divided by the change in x-coordinates between two points on the curve. To find the equation of the secant line, you need to determine two points on the curve and calculate their coordinates. Then, use the slope formula to find the slope of the line. Finally, use the slope-intercept form of a linear equation, y = mx + b, where m is the slope and b is the y-intercept, to write the equation of the secant line.
