When it is easier to use the point-slope form to write the equation of a line and when it is easier to use the slope-intercept form?
Step 1. Explain when to use the point-slope form.
The point-slope form of the equation of the line is . To write the equation in point-slope form, there shoud be given slope and one point.
Therefore, if one point and the slope are given, it is easier to use the point-slope form to write the equation of line.
Step 2. Explain when to use the slope-intercept form.
The slope-intercept form is . Where is slope and is intecept. So, to write the equation of line, there should be a slope and a intercept.
Therefore, while slope and intercept is given, it's easier to use the slope-intercept form to write the equation of line.
