Answer:

y = - 3x + 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 3 , thus

y = - 3x + c ← is the partial equation

To find c substitute (4, - 5) into the partial equation

- 5 = - 12 + c ⇒ c = - 5 + 12 = 7

y = - 3x + 7 ← equation of line

Write an equation of the line that passes through the given point and is parallel to the given line.
saveliy_v [14]

the equation of line passing through given point parallel to y = -2x+7 is: y = -2x+9

Step-by-step explanation:

Given equation of line is:

y = -2x+7

As the given line is in slope intercept form, the coefficient of x is the slope

Let m1 be the slope of given line

m_1 = -2

Let m2 be the slope of second line then

m_2= -2

The equation of line is given by:

y= m_2x+b

Putting the value of slope

y = -2x+b

Putting the point (4,1) in the equation

y = -2x+b\\1 = -2(4)+b\\1= -8+b\\b = 1+8\\b = 9

Putting the value of b in the equation

y = -2x+9

Hence,

the equation of line passing through given point parallel to y = -2x+7 is: y = -2x+9

A linear regression was conducted on the number of cigarettes a person smokes in a day versus the number of times they cough in
makvit [3.9K]

Answer:

a) response variable

Step-by-step explanation:

The response variable is the variable that depends on other variables such as the independent or explanatory variable, it is the variable that is being tested. The response variable is also called the dependent variable.

In linear regression, the y variable is referred to as the response variable while the x variable is referred to as the explanatory or independent variable.

In this case the y variable is "the number of times they cough in a day" and this variation depends on the x variable "number of cigarettes a person smokes in a day".
