\( y = -\frac{5}{4}x + 9 \)
Solución
To convert the equation \(10x + 8y = 72\) into slope-intercept form (\(y = mx + b\)), follow these steps:
1. **Isolate the \(y\)-term:**
\[
8y = -10x + 72
\]
2. **Solve for \(y\) by dividing every term by 8:**
\[
y = \frac{-10}{8}x + \frac{72}{8}
\]
3. **Simplify the fractions:**
\[
y = -\frac{5}{4}x + 9
\]
**Final Answer:**
\[
y = -\frac{5}{4}x + 9
\]

To convert the equation \( 10x + 8y = 72 \) into slope-intercept form (which is \( y = mx + b \)), we need to isolate \( y \). First, subtract \( 10x \) from both sides: \[ 8y = -10x + 72 \] Next, divide every term by \( 8 \) to solve for \( y \): \[ y = -\frac{10}{8}x + \frac{72}{8} \] Now simplify the fractions: \[ y = -\frac{5}{4}x + 9 \] So, the slope-intercept form is: \[ y = -\frac{5}{4}x + 9 \]
