Converting Slope-Intercept to Standard Form Equations

The Organic Chemistry Tutor

This instructional video provides a comprehensive, step-by-step tutorial on converting linear equations from slope-intercept form ($y = mx + b$) to standard form ($Ax + By = C$). The narrator guides viewers through a progression of problems, starting with simple integer equations and advancing to complex examples involving fractions with unlike denominators. The video emphasizes the algebraic rules required for standard form, specifically ensuring that the $x$ and $y$ variables are on the left side of the equation, the constant is on the right, and that coefficients are integers rather than fractions. Key themes include algebraic manipulation, the properties of equality, finding the least common multiple (LCM) to clear fractions, and the conventions of standard form notation. The video demonstrates specific techniques such as multiplying an entire equation by a denominator to eliminate fractions and multiplying by -1 to ensure the leading coefficient ($A$) is positive, a common requirement in algebra standards. For educators, this resource serves as an excellent tool for differentiating instruction in Algebra I classrooms. It can be used to support students who struggle with fraction operations within algebraic contexts or as a flipped classroom asset. The clear visual work and deliberate pacing allow students to follow the logic of each transformation, making it valuable for remediation, homework support, or exam review regarding linear equations.
