Write an equation in point slope form for a line that includes the origin and (9,-3)

Mathematics

So we are given two points that the line crosses, the origin and (9, -3), we can calculate the slope m of the line with these data, dividing the y segment by the x segment:
m = (-3 - 0)/(9 - 0) = -3/9
m = -1/3
then we can use the point slope line equation to find the line equation, lets use the point origin (0,0) to do so:
y - y1 = m(x - x1), where x1, y1 are the coordinates of a point that the line crosses:
y - 0 = (-1/3)(x - 0)
y = <span>(-1/3)x
so this is the equation of the line, slope  -1/3 and y intercept 0</span>

In interpreting a boxplot of a data set we note that the median is to the left of the center of the and the right line is longer
pantera1 [17]

Answer:

Option A

Step-by-step explanation:

When the median is to the left of the center of the distribution with the right line longer than the left, we can conclude that the data is skewed to the right. Here the mean is larger than the median thus skewing the distribution to the right.

Representing this on an histogram including data will show a better description and also indica the longer right line.

The system shown has _____ solution(s).
loris [4]
This system has one solution. Here are my steps to solving this problem:

y=x+1

2(x+1) - x = 2

2x +2 - x = 2

2x - x + 2 = 2

x + 2 = 2
    - 2  - 2
----------------
x = 0

y = 0 + 1
y = 1 

I hope this helps you!

A normal distribution has a mean 20 and standard deviation 5. What is the z score that corresponds to the value x=222
sashaice [31]

Answer: The z score that corresponds to the value x=22 is 0.4 .

Step-by-step explanation:

Given : A normal distribution has a mean 20 and standard deviation 5.

i.e. \mu=20

\sigma=5

Let x be the random selected variable.

We know that to find the z-score corresponds to the value x is given by :-

z=\dfrac{x-\mu}{\sigma}

For x = 22, we have

z=\dfrac{22-20}{5}=\dfrac{2}{5}\\\\\Rightarrow\ z=0.4

Hence, the z score that corresponds to the value x=22 is 0.4
