(-1,7);, (8,-2) write an equation of the line that passes

ruslelena [56]

The formula to find the slope of a line is m = $\frac{y_2 - y_1}{x_2 - x_1}$ where the x's and y's are your given coordinates and m is your slope. So, plug in your coordinates and solve.

m = <span> $\frac{y_2 - y_1}{x_2 - x_1} Plug in your coordinates m = [tex] \frac{-2 - 7}{8 - -1} Cancel out the double negative m = [tex] \frac{-2 - 7}{8 + 1} Simplify m = [tex] \frac{-9}{9} Divide m = -1 Now, plug that slope and one set of your given coordinates into point-slope form, [tex]y - y_1 = m(x - x_1)$ . I'll use (-1, 7).

<span> $y - y_1 = m(x - x_1)$ Plug in your points and slope
</span>y - 7 = -1(x - -1) Cancel out the double negative
y - 7 = -1(x + 1) Use the Distributive Property
y - 7 = -x - 1 Add 7 to both sides
y = -x + 6 </span>

a recycling bin is in the shape of a rectangular box find the height of the box if it's length is 18 ft its width is 8 feet and

OLEGan [10]

<h2>Answer:</h2>

The height of the box is:

4 ft.

<h2>Step-by-step explanation:</h2>

Let "h" denotes the height of the box.

Length of box is denoted by "l"

and breadth or width of box is denoted by "b"

We are given l=18 ft

b=8 ft.

Also we are given surface area of rectangular box= 496 ft²

As we know that the surface area of box is given by:

$Surface\ Area=2(lb+bh+hl)$

i.e.

$496=2(18h+8h+144)\\\\i.e.\\\\\\496=2(26h+144)$

Divide both side by 2.

$248=144+26h\\\\i.e.\\\\26h=248-144\\\\i.e.\\\\26h=104$

on dividing both side by 26 we get:

$h=4$

Hence, the height of the box is:

4 ft.

so it'd be the first, third and fourth one. all you gotta do is draw a vertical line through the middle of the 1st, 3rd and 4th.

What is slop of the line that passes through the ponitss (5, -4) and (7, -4)

mylen [45]

Answer:

The slope is 0

Step-by-step explanation:

Points on the graph:

(5, -4) and (7, -4)

Slope:

m=(y2 - y1)/(x2 - x1)

m=(-4 + 4)/(7 - 5)

m= 0/2

m=0
