The equation of the line is given as \( y = 8x \), where \( y \) represents the price in dollars and \( x \) represents the length of fabric in meters.
To find the unit rate for the price to the length of the fabric, you can think of the coefficient of \( x \) in the equation \( y = mx \) (where \( m \) is the unit rate) as the price per meter of fabric.
From the equation \( y = 8x \), the coefficient \( 8 \) indicates that the price is $8 for every 1 meter of fabric.
So, the unit rate for the price to the length of the fabric is:
\[ 8 \text{ dollars/meter} \]
Thus, the answer is:
\[ 8 \text{ } / \text{ m} \]
