Find the slope of the line that passes through the two points (0,1) and (-8, -7)
Crazy boy [7]

Answer:

<h3>The slope of the line is 1</h3>

Step-by-step explanation:

The slope of a line is found by using the formula

m =  \frac{y2 - y1}{x2 - x1}

where

m is the slope and

(x1 , y1) and ( x2 , y2) are the points

Substituting the above values into the above formula we have

Slope of the line that passes through

(0,1) and (-8, -7) is

m =  \frac{ - 7 - 1}{ - 8 - 0}  =  \frac{ - 8}{ - 8}  = 1

<h3>The slope of the line is 1</h3>

Hope this helps you

The length of a banquet table is 4 feet longer than 6 times its width. If the perimeter is 78 feet, what are the dimensions of t
harina [27]
Hello,
2(l+w)=78
Divided 2 from both side
2(l+w)/2=78/2
l+w=39 feet

l=6w+4
Replace l with 6w+4

6w+4+w=39
7w+4=39
Subtract 4 from both side
7w=35
Divided 7 from both side
w=5 feet
l=6w+4
l=6(5)+4
l=30+4
l=34 feet. As a result, the length of the rectangle is 34 feet and the width of rectangle is 5 feet. Hope it help!
