WebThe "General Form" of the equation of a straight line is: Ax + By + C = 0. A or B can be zero, but not both at the same time. The General Form is not always the most useful form, and you may prefer to use: The Slope-Intercept Form of … WebThe Slope-Intercept Formula y = mx + b; As the names imply the form that you use is dependant on the information you are given to start with. Example 1: Find the equation of the line that has a slope of and contains the point (2, -1). 1 3. Solution. Since the information given is a point and the slope, the point slope formula is used.
