Step 2.1

Apply the distributive property.

$y = 0.5 \cdot 1 + 0.5 (- x)$

Step 2.2

Simplify the expression.

Step 2.2.1

Multiply $0.5$ by $1$ .

$y = 0.5 + 0.5 (- x)$

Step 2.2.2

Multiply $- 1$ by $0.5$ .

$y = 0.5 - 0.5 x$

Step 2.2.3

Reorder $0.5$ and $- 0.5 x$ .

$y = - 0.5 x + 0.5$

$y = - 0.5 x + 0.5$

$y = - 0.5 x + 0.5$
