The rule is: y=|x|. mark all of these points (x,y) on a coordinate grid.

Answer:
see attached image
Step-by-step explanation:
One way to get a sense of the graph is to pick integers and make a table of function values.
- x = -3 y = |-3| = 3 Point (-3, 3)
- x = -2 y = |-2| = 2 (-2, 2)
- x = -1 y = |-1| = 1 (-1, 1)
- x = 0 y = |0| = 0 (0, 0)
- x = 1 y = |1| = 1 (1, 1)
- x = 2 y = |2| = 2 (2, 2)

Sqrt242 can't be simplified anymore. It doesn't contain any perfect squares factors. For instance,
This can be simplified because
And 25 is a perfect square, and square root of 25 is 5. The simplified version for this would be 5 sqrt (6). For your question, sqrt 242 can't be simplified anymore, its most simplified version is its current state.

Answer:
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
