Standard Form Equation:
From: | To: |
The standard form of a linear equation is Ax + By = C, where A, B, and C are integers with no common factors (other than 1), and A is non-negative. It's useful for finding both x and y intercepts easily.
The calculator displays the equation in standard form:
Where:
Explanation: The standard form is particularly useful for analyzing linear equations and finding intercepts quickly.
Details: The standard form makes it easy to find both x and y intercepts (set y=0 to find x-intercept, x=0 to find y-intercept). It's also the preferred form for many linear algebra operations.
Tips: Enter the coefficients A, B, and the constant C. The calculator will display the complete equation in standard form. All values can be positive or negative numbers.
Q1: Why is A typically non-negative in standard form?
A: By convention, we prefer to write the equation with A ≥ 0 to maintain consistency, though mathematically negative values are equivalent.
Q2: How do I convert slope-intercept form to standard form?
A: Move all terms to one side of the equation (e.g., from y = mx + b to -mx + y = b), then adjust coefficients to be integers.
Q3: What if A, B, and C have common factors?
A: For true standard form, you should divide all terms by their greatest common divisor to simplify the equation.
Q4: Can B be zero in standard form?
A: Yes, if B=0 you get a vertical line (Ax = C). Similarly, if A=0 you get a horizontal line (By = C).
Q5: How do I find the slope from standard form?
A: The slope m = -A/B (when B ≠ 0). For B=0, the line is vertical with undefined slope.
