Write the equation's of the lines using the given information 1. m=-2, (3, -7)
2. m=1/4, (4, 3)
3. (-1, 0),b=3
4. m=0, (2, -1)
5. m=-2/3,(6, -3)
6. m is undefined,(3, 2)
7. (0, 4), (4, 7)
8. (1/2, 3),(1, 11/2)

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
