Answer:

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)\\
