Answer

The standard form of the equation \( y = \frac{2}{3}x - 6 \) is \( 2x - 3y = 18 \).

Solution

To convert the equation \( y = \frac{2}{3}x - 6 \) into **standard form**, we follow these steps: **Standard Form of a Linear Equation:** \[ Ax + By = C \] where \( A \), \( B \), and \( C \) are integers, and \( A \) is non-negative. **Steps to Convert:** 1. **Start with the given equation:** \[ y = \frac{2}{3}x - 6 \] 2. **Eliminate the fraction by multiplying every term by 3:** \[ 3y = 2x - 18 \] 3. **Rearrange the equation to get all variable terms on one side and constants on the other:** \[ 2x - 3y = 18 \] **Final Standard Form:** \[ 2x - 3y = 18 \] **Matching with the Given Options:** - **A.** \( 3y = 2x - 18 \) - **B.** \( 2x - 3y = 18 \) - **C.** \( 3y = 2x - 6 \) - **D.** \( 2x - 3y = 6 \) - **E.** \( -2x + 3y = 6 \) **Correct Answer:** **B. \( 2x - 3y = 18 \)**

To write the equation \( y = \frac{2}{3} x - 6 \) in standard form, we want to rearrange it into the form \( Ax + By = C \), where \( A \), \( B \), and \( C \) are integers. Starting with the given equation: \[ y = \frac{2}{3} x - 6 \] First, we can eliminate the fraction by multiplying the entire equation by 3: \[ 3y = 2x - 18 \] Now, we can rearrange this to standard form by simply moving \( 2x \) to the left side: \[ -2x + 3y = -18 \] To make \( A \) positive, multiply through by -1: \[ 2x - 3y = 18 \] Matching this with the options provided: The correct answer is \( B. \, 2x - 3y = 18 \). The other possible options include incorrect coefficients or the wrong constant on the right side.
