Does anyone know this?

To find the slope of the line, use the slope formula (m is the slope):

      And plug in the two points

(-4, 11) = (x₁, y₁)

(-2, 3) = (x₂, y₂)

  [two negative signs cancel each other out and become positive]

   Simplify

m = -4        Your answer is A

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
