Hi there!  When talking about interval notation, we use regular parentheses e.g. (). Interval notation is a way to describe continuous sets of real numbers by the numbers that bound them. When written, they look somewhat like ordered pairs. Although, they are not meant to denote a specific point. They are meant to be a shorthand way to write an inequality or system of inequalities.

With interval notation, we use use square brackets e.g. [ ].

With inequalities, we use "less than or equal to" ≤ or "greater than or equal to": ≥ to include the endpoint of the interval. Inclusive inequalities with the “or equal to” component are indicated with a closed dot on the number line and with a square bracket using interval notation. Strict inequalities without the “or equal to” component are indicated with an open dot on the number line and a parenthesis using interval notation

Hope this helps! Have a good day!!

Data was collected on the number of pets and the height of a random group of students. Identify the correlation you would expect
Ipatiy [6.2K]
No correlation
A scatterplot is used to represent a correlation between two variables. There are two types of correlations: positive and negative. Variables that are positively correlated move in the same direction, while variables that are negatively correlated move in opposite directions.

Confused someone help

Answer:

y = -5x - 21

Step-by-step explanation:

Given in the question,

equation of a parallel line

y = -5x + 6

point through which it passes

(-4,-1)

Step1

Find the gradient of the equation given, as it is parallel so it will have same gradient

equation of straight line

y = mx + c

where m is gradient

            c is y intercept

y = -5x + 6

m =-5

Step2

Find y-intercept

-1 = -5(-4) + c

-1 = 20 + c

c = -20 - 1

c = -21

Step3

form the equation

y = -5x - 21
