<h3>What is the equation of a line passing through two given points in 2 dimensional plane?</h3>

Suppose the given points are (x_1, y_1) and (x_2, y_2), then the equation of the straight line joining both two points is given by

(y - y_1) = \dfrac{y_2 - y_1}{x_2 - x_1} (x -x_1)

The equation of the line is found as;

\rm y-y_1=  \frac{y_2-y_1}{x_2-x_1}      \\\\ \rm y-9=                                         \frac{31-9}{2+5} (x+5)\\\\ 7y-63 = \frac{31-9}{2+5} (c+5)\\\\ 7y-63=22x+110\\\\ 7y= 22x+173 \\\\ but ,x=13\\\\ 7y=22 \times 13 +173\\\\ y= \frac{1259}{7} \\\\ y= 179

Samples of viewers were taken from two different movies to compare the ages of those
astraxan [27]

Answer:

The median are equal

Step-by-step explanation:

Given

I will answer this question with the attached plot (see attachment 2)

Required

The equal statistical measures

See attachment 1 on how to read a box plot

Using attachment 1 as a guide, we have the following observation

<u>Movie 2</u>                                                   <u>Movie 1</u>

Minimum=7.5                                      Minimum=10

Q_1 = 22.5                                                 Q_1 = 15

                                  Median = 30

Q_3 = 35                                                   Q_3 = 40

Maximum = 47.5                                    Maximum = 52.5

By comparison, they have equal median (30)

Solve the following equations. 2x - y = 8 3x + y = 17​
aleksley [76]
<h2>Answer: (5, 2)</h2>

<h2>System of equations:</h2>

2x - y = 8

3x + y = 17

<h2>Solve for x:</h2>

2x - y = 8

3x + y = 17

________ +

5x = 25

x = 5

<h2>Plug in x to one of the equations to solve for Y</h2>

2(5) - y = 8

10 - y = 8

-y = -2

y = 2
