Understanding Equations in Different Forms

This video tutorial covers how to write equations in three different forms: point-slope, slope-intercept, and standard form. It begins with finding the slope using two given points, then demonstrates how to derive the equation in point-slope form. The tutorial continues by converting the equation to slope-intercept form and finally to standard form, ensuring all steps are clear and fractions are simplified.

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

• Point-slope, slope-intercept, and standard

• Quadratic, linear, and cubic

• Exponential, logarithmic, and trigonometric

• Polynomial, rational, and radical

• 3x - 2y = 12

• 3x + 2y = 12

• 2x - 3y = 12
