Answer:

Step-by-step explanation:

slope (k) is the rise over run of the line

a way of finding the slope if you have two dots of the line is:

$k \: = \frac{y2 - y2}{x2 - x2}$

here the dots that belong to the line that you can most easily see are:

A(-6,0)

B(0,6)

by inserting the values into the euquation you get:

$\frac{6 - 0}{0 - ( - 6)} = \frac{6}{6} = 1$

good luck with your maths solving

A box with a square base and no top is to be built with a volume of 4000 in3. find the dimensions of the box that requires the l

vekshin1

Let the length of the square base be x inches .

And the height of the box be y inch .

Volume = x*x*y

4000 = x *x *y

$y = \frac{4000}{x^2}$

S = x*x + 2xy + 2 x y

$S = x^2 + 4 xy$

$S = x^2+ 4x* \frac{4000}{x^2}$

$S = x^2 + \frac{16000}{x}$

$S ' = 2x - \frac{16000}{x^2}$

S ' =0

$2x - \frac{16000}{x^2}=0$

$2x^3 - 16000 = 0$

$x^3 = 8000$

x = 20

$y = \frac{4000}{20^2} = \frac{4000}{400} = 10$

Answer:

1. Slope: -3/4

2. Point-slope: y+4=-3/4(x+4)

3. Slope-intercept: y=-3/4x-7

4. Standard form: 3x+4y=-28

Step-by-step explanation:

1. To find the slope, use the slope formula, which is: y2-y1/x2-x1.

Plug the y-coordinates into the top part of the equation and the x-coordinates into the bottom part.

2--4/-4-4

2+4/-8 = 6/-8, or 3/-4

2. Use the slope and one of the x and y coordinates to put the equation into point-slope form. Recall that point-slope form is: y-y1=m(x-x1). Let's use the coordinates (4,-4).

y+4=-3/4(x+4)

3. To put the point-slope equation into slope-intercept form (y=mx+b), you need to distribute -3/4 to x+4 and subtract 4 from both sides.

When you distribute, the equation becomes:

y+4=-3/4x-3

Finally, when you subtract 4, the equation becomes:

y=-3/4x-7

4. Standard form is written as x+y= #.

To convert y=mx+b to standard form, first subtract -3/4x from both sides.

-3/4x + y = -7

Multiply everything by 4

3x + 4y = -28
