The image shows a partial calculation where $x=1$ is substituted into an expression related to the equation $x - 2y = 2$ .

Identify the equation and substitution.
The expression shown is $x - 2y - 2$ . If this expression is set to zero, it represents the equation $x - 2y = 2$ .
The student has substituted $x = 1$ into this expression, resulting in $1 - 2y - 2$ .
Solve for $y$ .
We set the expression equal to zero to find the corresponding $y$ value for the line $x - 2y = 2$ :
$1 - 2y - 2 = 0$
Combine the constant terms:
$-1 - 2y = 0$
Add 1 to both sides:
$-2y = 1$
Divide by $-2$ :
$y = \frac{1}{-2}$ $y = -0.5$
The value $y = 0.5$ shown at the top of the image is incorrect for this calculation. The correct value is $y = -0.5$ .

The final answer is $-0.5$ .
