What is the slope of the line containing (–2, 5) and (4, –4)?
kotykmax [81]
<span>To find the slope of a line use the Point Slope Formula which is: (y2-y1) / (x2-x1)

The point with the bigger x value is (x2,y2)

Next, plug the two points into the formula: (-4 - 5) / (4 -(-2))

Note: 4-(-2) = 4+2 = 6
Simplify: -9 / 6 = - 3/2
The answer is B.

Hope this helps, and May the Force Be With You!

Answer:

width = 40 feet, length = 90 feet

Step-by-step explanation:

length = 2w + 10

width = w

Perimeter = 260

Perimeter of rectangle = 2length + 2width

Sub the values into that equation:

260 = 2(2w + 10) + 2(w)

260 = 4w + 20 + 2w

260 = 6w + 20

260 - 20 = 6w

240 = 6w

w = 240/6

w = 40

So now we know the width of the garden is 40 feet.

To find the length, substitute the width into the length equation:

length = 2w + 10

length = 2(40) + 10

length = 90 feet

length = 90 feet, width = 40 feet
