Solution
Solution Steps
To express the given equation in slope-intercept form (y = mx + b), we need to solve for y in terms of x. This involves isolating y on one side of the equation.
Step 1: Start with the Given Equation
We start with the given equation:
\[ 17x - 10y = 80 \]
Step 2: Isolate \( y \)
To express the equation in slope-intercept form (\( y = mx + b \)), we need to isolate \( y \). We do this by solving for \( y \) in terms of \( x \):
\[ 17x - 10y = 80 \]
\[ -10y = -17x + 80 \]
\[ y = \frac{17}{10}x - 8 \]
Step 3: Identify the Slope and Intercept
From the equation \( y = \frac{17}{10}x - 8 \), we can identify the slope \( m \) and the y-intercept \( b \):
\[ m = \frac{17}{10} \]
\[ b = -8 \]
Final Answer
The equation in slope-intercept form is:
\[ y = \frac{17}{10}x - 8 \]
Comparing this with the given choices, the correct answer is:
\[ \boxed{C} \]
