What is the rate of change of the linear relationship modeled in the table (-2,5) (-1,4) (0,3) (1,2)
poizon [28]

The rate of change of the linear relationship is -1.

Explanation:

It is given that there is a linear relationship between all these points, these points lie on a straight line.

The equation to find the slope passing through two points \left(x_{1}, y_{1}\right) and \left(x_{2}, y_{2}\right) is given by

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Substituting the points (-2,5) and (-1,4), we get,

\begin{aligned}m &=\frac{4-5}{-1+2} \\&=\frac{-1}{1} \\&=-1\end{aligned}

Thus, the slope is -1.

Thus, the rate of change of the linear relationship is -1.

FIND THE MEDIAN OF THE DATA SET3,35,23,37,45,49,27,48<br> A.35<br> B.34<br> C.30.2<br> D.38
mojhsa [17]

Answer:

A. 35

Step-by-step explanation:

The median of a data set is the middle value when the data values are placed in order of size.

<u>Given data set</u>:

  • {3, 35, 23, 37, 45, 5, 49, 27, 48}

Place the data in <u>order of size</u>:

  • {3, 5, 23, 27, 35, 37, 45, 48, 49}

To find the median, divide the total number of data values (n) by 2.

  • If n/2 is a whole number, the median is halfway between the values in this position and the position above.
  • If n/2 is not a whole number, round it up to find the position of the median.

As there are 9 data values, the median value is:

\implies \dfrac{9}{2}=4.5 \implies \sf 5th\;value

Therefore, the median of the given data set is 35.

Please state the equation of the line in standard form
kramer

Answer:

See below

Step-by-step explanation:

Slope = rise / run

           from 0,-1   to  1.5 , 0

               this is    1 / 1.5    =   2/3

y xis intercept = -1

y = 2/3 x   -1            Slope intercept form

2/3 x - y   = 1             another form

<u>2x - 3y = 3                Standard form (I think this is 'standard form' ....yah?) </u>
