Provide an appropriate response.Describe a situation in which it would be more convenient to use the point-slope form of the equation of a line than the slope-intercept form.
What will be an ideal response?
Answers will vary. One possibility: Slope-intercept form works well if you know the slope of the line and the y-intercept. However, point-slope form is more convenient if you know the slope of the line and a point that is not the y-intercept.
