Question

I need with these problems

Answer 1

1.
`(5)/(6)`

3.
`(7)/(0)` (undefined slope)

5.
`-(7)/(4)`

7.
`24`

Explanation:

slope (m)

rate of change (r)

1. m =
`(y_2-y_1)/(x_2-x_1)=(8-3)/(13-7) =(5)/(6)`

3. m =
`(y_2-y_1)/(x_2-x_1)=(4-(-3))/(9-9) =(7)/(0)` (undefined slope)

5. m =
`(y_2-y_1)/(x_2-x_1)=(-1-6)/(0-(-4)) =(-7)/(4)=-(7)/(4)`

7. r =
`(f(b)-f(a))/(b-a)=(24-0)/(1-0)=(24)/(1)=24`

Hope this helps!
