$y = x - 9$

#### Explanation:

$y = x + 4$
Slope m is the coefficient of x.
$\therefore m = 1$
Line parallel to this line will also have the same slope '1'.
Given slope and a point on the st line, form of the equation is
$\left(y - y 1\right) = m \left(x - x 1\right)$ where x1 = 7 and y1 = -2.
$\therefore \left(y - \left(- 2\right)\right) = 1. \left(x - 7\right)$
$y + 2 = x - 7$
$y = x - 9$
