Can you solve this problem please​

k = 11

Step-by-step explanation:

Given the points are collinear then the slopes between consecutive points are equal.

Using the slope formula

m =

with (x₁, y₁ ) = (5, 1) and (x₂, y₂ ) = (1, - 1)

m = = =

Repeat with another 2 points and equate to

with (x₁, y₁ ) = (1, - 1) and (x₂, y₂ ) = (k, 4)

m = , then

= ( cross- multiply )

k - 1 = 10 ( add 1 to both sides )

k = 11

my acc plz
