What is Standard Form? | Understanding Ax + By = C (Part 1)
Welcome to Standard Form Part 1! This video introduces standard form of linear equations (Ax + By = C) and teaches you when to use it versus slope-intercept form.
📊 In This Video:
What is standard form? (Ax + By = C)
When to use standard form vs slope-intercept form
Identifying "rate + rate = total" scenarios
Writing standard form equations from word problems
Finding solutions to standard form equations
Converting standard form to slope-intercept form
🔑 Key Differences:
Slope-Intercept (y = mx + b): ONE rate + start amount
Standard Form (Ax + By = C): TWO rates + total
📝 Real-World Examples Covered:
Baseball ticket sales (students & adults)
Video game points (stars & jewels)
Shopping (shirts & jeans)
Working with coins and bills
