Answer:

25)

v - 6(4v + 6) = - 82

v - 24v - 36 = - 82

v - 24v = - 82 + 36

- 23v = - 46

- v = - 46/23

- v = - 2

26)

- 96 = 4(6n - 6)

- 96 = 24n - 24

- 96 + 24 = 24n

- 72 = 24n

- 72/24 = n

- 3 = n

27)

- 2(- 5a - 2) = 84

10a + 4 = 84

10a = 84 - 4

10a = 80

a = 80/10

28)

7(7 + 3k) = 217

49 + 21k = 217

21k = 217 - 49

21k = 168

k = 168/21

Find the slop of the line passing through the given points (2,3),(-1,-6)

professor190 [17]

Slope is rise over run

I would suggest writing the coordinate that is farthest to the left first so it is easier to visualize (-1,-6),(2,3)
as you go to the right, it goes over three, and up 9
9/3 simplifies to 3
the slope is 3
