The lines are perpendicular. I used Desmos Graphing Calculate to graph the lines.

Answer:

$y = \frac{1}{-1}x + 0$ $or$ $y = \frac{1}{-1}x$

Step-by-step explanation:

$y = mx + c$

$m = \frac{y_{2} -y_{1}}{x_{2} - x_{1} } }$

$(x_{1},y_{1}) = (-1,1)\\(x_{2},y_{2}) = (-2,2)$

$m = \frac{2 - 1}{(-2) - (-1)}$

$m = \frac{2 - 1}{-2 +1 }$

$m = \frac{1}{-1}$

$c = 0$

$y = \frac{1}{-1}x + 0$ $or$ $y = \frac{1}{-1}x$
