Answer

**Transformed Equation:** - **Slope-Intercept Form:** \( y = -\frac{3}{2}x + 9 \) - **Two Intercepts Form:** \( \frac{x}{6} + \frac{y}{9} = 1 \)

Solution

**Step 1. Write the given equation:** \[ 3x + 2y - 18 = 0 \] --- **(a) Slope-Intercept Form \(\left(y = mx + c\right)\):** 1. Isolate the \(y\)-term: \[ 2y = -3x + 18 \] 2. Divide by \(2\): \[ y = -\frac{3}{2}x + 9 \] Thus, the slope-intercept form is: \[ y = -\frac{3}{2}x + 9 \] --- **(b) Two Intercepts Form \(\left[\frac{x}{a} + \frac{y}{b} = 1\right]\):** 1. Find the \(x\)-intercept by letting \(y = 0\): \[ 3x - 18 = 0 \quad \Rightarrow \quad 3x = 18 \quad \Rightarrow \quad x = 6 \] So, \(a = 6\). 2. Find the \(y\)-intercept by letting \(x = 0\): \[ 2y - 18 = 0 \quad \Rightarrow \quad 2y = 18 \quad \Rightarrow \quad y = 9 \] So, \(b = 9\). 3. Substitute into the intercept form: \[ \frac{x}{6} + \frac{y}{9} = 1 \] --- **Final Answers:** - Slope-Intercept Form: \(\displaystyle y = -\frac{3}{2}x + 9\) - Two Intercepts Form: \(\displaystyle \frac{x}{6} + \frac{y}{9} = 1\)

The Deep Dive

To convert the equation \( 3x + 2y - 18 = 0 \) into slope-intercept form, we solve for \(y\). Rearranging gives us \(2y = -3x + 18\). Dividing by 2 yields \(y = -\frac{3}{2}x + 9\). Here, the slope \(m\) is \(-\frac{3}{2}\) and the y-intercept \(c\) is \(9\). For the two-intercepts form, we rewrite the original equation as \(3x + 2y = 18\). To find the x-intercept, set \(y=0\): \(3x = 18\) results in \(x=6\). For the y-intercept, set \(x=0\): \(2y = 18\) gives \(y=9\). So, the equation becomes \(\frac{x}{6} + \frac{y}{9} = 1\).
