Slope-intercept form follows the format: y=mx+b, where m is the slope and be is the y-intercept.


First, find the slope using the equation: y2-y1/x2-x1.  In this question, x1=9, x2=-2, y1=2, and y2=6.  Plug in, solve, and simplify to find the slope:

6-2/-2-9

4/-11

m=-4/11


Now, the equation looks like y=-4/11x+b.  To find be, you can plug in the values from one set of the coordinates for x and y in the equation and solve for b.  The coordinate pair you choose does not matter, but I will use (9,2).

2=-4/11(9)+b

2=-36/11+b

58/11=b


The equation of the line in slope-intercept form is y=-4/11x+58/11.


Hope this helps!!

How to <br> Write <br> 3/9<br> in simplest form.
White raven [17]
To write it in simplest form, you must find a common factor.

In \frac{3}{9}, 3 is a factor of both 3 and 9

3÷3=1 and 9÷3=3

So \frac{3}{9} =  \frac{1}{3}

\frac{1}{3} is your answer in simplest form.

A sports stadium has 10000 seats, divided into box seats, lower-deck seats, and upper-devk seats. Box seats sell for 10 dollars,
lesantik [10]

Answer:

Number of box seats = 1000

Number of lower deck seats = 5000

Number of upper deck seats = 4000

Step-by-step explanation:

Let number of box seats = x

Let number of lower deck seats = y

Let number of upper deck seats = z

As per question statement:

x+y+z=10000 ...... (1)

Cost for box seat = $10

Cost for x box seats = 10x

Cost for lower deck seat = $8

Cost for y lower deck seats = 8y

Cost for lower deck seat = $5

Cost for z lower deck seats = 5z

As per question statement:

10x+8y+5z=70000 ..... (2)

z = 4x ..... (3)

Putting value of y in (1) and (2):

x+y+4x=10000\\\Rightarrow 5x+y=10000 ....... (4)

10x+8 y+5\times 4x=70000\\\Rightarrow 30x+8y=70000 ..... (5)

8 \times (4) - (5):

10x =10000

\Rightarrow x = 1000

By (3):

z = 4000

Now, by equation (1):

y = 5000

Number of box seats = 1000

Number of lower deck seats = 5000

Number of upper deck seats = 4000
