Solution Steps

To determine if the equation is linear, we need to simplify the given equation and check if it can be expressed in the form ax + by = c, where a, b, and c are constants. If it can be expressed in this form, it is linear. If it is linear, we will rearrange the terms to convert it to the standard form.

Step 1: Simplifying the Equation

We start with the equation:

\[ (-5 + y)^2 - y^2 = -11x + 5 \]

Expanding the left side, we have:

\[ (-5 + y)^2 = y^2 - 10y + 25 \]

Thus, the equation becomes:

\[ y^2 - 10y + 25 - y^2 = -11x + 5 \]

This simplifies to:

\[ 25 - 10y = -11x + 5 \]

Step 2: Rearranging to Standard Form

Next, we rearrange the equation to the standard form \( ax + by = c \):

\[ 11x - 10y = 25 - 5 \]

This simplifies to:

\[ 11x - 10y = 20 \]

Step 3: Determining Linearity

Since we can express the equation in the form \( ax + by = c \) with \( a = 11 \), \( b = -10 \), and \( c = 20 \), we conclude that the equation is linear.

Final Answer

The equation is linear, and its standard form is:

\[ \boxed{11x - 10y = 20} \]
