Step-by-step explanation:

A(-1,2) and B(3,3) then AB=(4,1).

Normal vector

n=(-1,4)

Our line contains point A(-1,2) and has normal vector n=(-1,4) is

(d) :  - 1(x + 1) + 4(y - 2) = 0

(d ):  - x - 1 + 4y - 8 = 0

(d) :  - x + 4y - 9 = 0

Answer:

1/4

Step-by-step explanation:

To find the slope of a line from two points we use

m = (y2-y1)/(x2-x1)

m = (3-2)/ (3--1)

   = (3-2)/(3+1)

  =1/4

kakasveta [241]

Answer:

-2

Step-by-step explanation:

y = kx + n

When you insert the given points you get

3k + n = 4 \\

7k + n =  - 4 \\

Than you multiply the first one by - 1 and sum it with the second to get rid of n

4k =  - 8 \\ k =  - 2
