Question

Can somone pls help me with this I have a C- in math and I really need help also a like show work on each one plsss

Answer 1

1.
`(3)/(8)`

2.
`(1)/(4)`

3a.
`-(1)/(4)`

3b. 3

3c.
`-(4)/(5)`

4.
`m = (y_1 - y_2)/(x_1-x_2)\\`

Explanation:

1.

Rises 6 inches for every horizontal change of 16 inches

Slope = rise/run

Slope = 6/16

Slope = 3/8

2.

Rises 3 feet for every horizontal change of 12 feet

Slope = rise/run

Slope = 3/12

Slope = 1/4

3a.

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

`m = (3-2)/(-2-2)`

`m = (1)/(-4)`

`m = -(1)/(4)`

3b.

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

`m = (-1 - 2)/(-1-0)`

`m = (-3)/(-1)`

`m = 3`

3c.

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

`m = (1 - (-3))/(-1-4)\\`

`m = (4)/(-5)\\`

`m = -(4)/(5)`

4.

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