What is the slope intercept form of (3,3) (7,-1)

kow [346]

Slope intercept form follows this general equation...
$y=mx+b$
With this information you have posted, all you can do is find slope, your m. To calculate for slope, you need to use this following equation...
$m= \frac{y_2-y_1}{x_2-x_1}$
Then, you pick one of your coordinate pairs to be 1 and the other to be 2. I will choose the first coordinate pair as 1, so...
$m=\frac{-1-3}{7-3} =-1$
You plug in -1 into your slope formula...
$y=-1x+b$
Now, to find your y-intercept, or b, you must plug in one of your coordinate pairs. In that equation, you may plug in the values (3,3), so you'll have...
$3=-1(3)+b$
Just solve for b and you will be done

A tank initially contains 20 gallons of water. If water is flowing into the tank at a rate of 0.1 L/sec what is the volume of wa

IRISSAK [1]

The total volume of water in the tank after 3 mins 24.75 gallons.

<h3>New volume of water in the tank</h3>

The new volume of water that entered into the tank is calculated as follows;

V₁ = 0.1 L/sec x (3 x 60 s)

V₁ = 18 L

<h3>Volume of water in liters to gallon</h3>

1 liter = 0.264 gallons

18 Liter = ?

= 18 x 0.264

= 4.75 gallons

<h3>Total volume of water in the tank after 3 mins</h3>

V = 20 gallons + 4.75 gallons

V = 24.75 gallons

a box with a square base is taller than it is wide. in order to send the box through the US mail, the height of the box and the

NemiM [27]

The given box has the shape of a <u>cuboid</u>, since its <em>height</em> is greater than its <em>width</em>. Thus, the <em>maximum volume</em> for such box is 11200 $in^{3}$ .

The <u>volume</u> of an object is a measure of it <em>containing</em> capacity. Since the given box has a taller <em>height</em> than its <em>width</em>, then it has the shape of a <em>cuboid</em>. The<u> volume</u> of a cuboid is given as:

volume = length x width x height

= area x height

Given that the <u>sum</u> of the <em>perimeter</em> of its base and its <em>height</em> is not more than 108 inches, we can say; let the sides of the <em>square</em> base be represented by l and its height by h.

Then;

4l + h = 108

Therefore, maximum volume for the box can be attained when l = 20 inches and h = 28 inches.

So that;

4(20) + 28 = 80 + 28

= 108 inches

Thus;

maximum volume = area of the square base x height

= 400 x 28

maximum volume = 11200 $in^{3}$

The <u>maximum</u> <u>volume</u> for such a box would be 11200 $in^{3}$ .
