Answer:

The diameter is 2

Step-by-step explanation:

We can use a ratio to solve

6              x

-------  = --------------

18.84      6.28

Using cross products

6 * 6.28 = 18.84x

Divide each side by 18.84

37.68/18.84 = x

2 =x

Complete the equation of the line through (-9,7) &amp; (-6,-3)
scZoUnD [109]

Answer:

y=-\frac{10}{3}x-23

Step-by-step explanation:

we have the points

(-9,7) and (-6,-3)

step 1

Find the slope

The formula to calculate the slope between two points is equal to

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

substitute the values

m=\frac{-3-7}{-6+9}

m=-\frac{10}{3}

step 2

Find the equation in point slope form

y-y1=m(x-x1)

we have

m=-\frac{10}{3}

(x1,y1)=(-6,-3)

substitute

y+3=-\frac{10}{3}(x+6)  ---> equation in point slope form

step 3

Find the equation of the line in slope intercept form

y=mx+b

we have

y+3=-\frac{10}{3}(x+6)

Isolate the variable y

Distribute right side

y+3=-\frac{10}{3}x-20

subtract 3 both sides

y=-\frac{10}{3}x-20-3

y=-\frac{10}{3}x-23
