Write the slope intercept form equation of the line given in graph

Answer:

y = 2/5x -2

Step-by-step explanation:

First, establish two points. I'll use the intercepts for this problem.

(5, 0), (0, -2)

To find slope, divide change in y by change in x.

Change in y --> 0 - (-2) = 2

Change in x --> 5 - 0 = 5

<em>Slope = 2/5</em>

<u>Next, find intercept.</u>

Plug in slope for one of the points and find how you can make that equal to the y coordinate by adding/subtracting

0 · 2/5 + ? = -2

? = -2

<em>y intercept = -2</em>

Or if the line intercepts the y-axis at a definite point like this graph, just find where it intercepts.

<u>Putting it Together</u>

Now just put this into slope-intercept form which is y = mx + b, where m is the slope and b is the y-intercept.

<em>y = 2/5x - 2</em>

Self storage center is a storage room that is 8 feet long 6 feet wide and 10 feet high what is the volume of the room
Cerrena [4.2K]

Answer:

480 cubic feet

Step-by-step explanation:

Given length of self storage = 8 feet

width of self storage = 6 feet

height of self storage = 10 feet.

Volume of rectangular object is calculated by formula

volume = length * width * height

substituting the value of  length , width and  height of  self storage room in above formula we have

volume of self storage room = 8 * 6* 10 cubic feet= 480 cubic feet

A music store buys instruments and then sells them for 30%more than they paid.
tamaranim1 [39]

Answer:

The store will sell the guitar for $58.50

Step-by-step explanation:

$45 * 1.3 = $58.50

Since the price they bought it for is $45 and the markup percent is 30%, we multiply $45 by 1.3, which will give us $58.50.
