find the equation of a line passing through the point -1 ,2 the perpendicular to x minus y + 2 equals to zero​

Answer 1

Answer:

$x + y = 1$

Step-by-step explanation:

$x - y + 2 = 0$

$y = x + 2$

$slope(m1) = 1$

if it's perpendicular then slope of required line must be

$- 1$

so that m1m2=-1
