Which of the following procedures correctly produces the equation of a line given intercepts (a, 0) and (0, b) where a and b are nonzero?

• A. Use the Intercept Form of a linear equation, which is defined as (x/a) + (y/b) = 1.
• B. Find the slope m = b/a and substitute it into the slope-intercept form y = mx + b.
• C. Calculate the slope m = -a/b and use the point-slope form with the point (0, b).
• D. Add the intercepts together to find the constant C in the equation Ax + By = C.

Answer: (A)
