Question

Can some one help me with one of these 5 problems plzz

Answer 1

Look at the pictures.

CL 2-109

The formula of a slope:

`m=(y_2-y_1)/(x_2-x_1)`

We have

`(-5,\ 7)\to x_1=-5,\ y_1=7\\(10,\ 1)\to x_2=10,\ y_2=1`

Substitute:

`m=(1-7)/(10-(-5))=(-6)/(10+5)=(-6)/(15)=-(2)/(5)`

Answer 2

I can help with CL 2-107. All you have to do is simplify the equation on both sides, and then isolate w to find its value.

6w - 5 + 8w - 2w - 3 = 9w - 24

(-5) + 12w - 3 = 9w - 24

-8 + 12w = 9w - 24

-8 + 3w = -24

3w = -16

w =
`(-16)/(3)`

w = -5.33

Hope that helps! Sorry I couldn't help with the other ones!
