What are the three forms of linear equations discussed in the video?

• Point-slope, slope-intercept, and quadratic forms

• Point-slope, slope-intercept, and standard forms

• Slope-intercept, quadratic, and cubic forms

• Standard, quadratic, and cubic forms

Why are there multiple forms of writing a linear equation?

• To confuse students
