Answer:

1. $\frac{3}{8}$

2. $\frac{1}{4}$

3a. $-\frac{1}{4}$

3b. 3

3c. $-\frac{4}{5}$

4. $m = \frac{y_1 - y_2}{x_1-x_2}\\$

Step-by-step explanation:

Rises 6 inches for every horizontal change of 16 inches

Slope = rise/run

Slope = 6/16

Slope = 3/8

Rises 3 feet for every horizontal change of 12 feet

Slope = rise/run

Slope = 3/12

Slope = 1/4

3a.

$m = \frac{y_1 - y_2}{x_1-x_2}$

$m = \frac{3-2}{-2-2}$

$m = \frac{1}{-4}$

$m = -\frac{1}{4}$

3b.

$m = \frac{y_1 - y_2}{x_1-x_2}\\$

$m = \frac{-1 - 2}{-1-0}$

$m = \frac{-3}{-1}$

$m = 3$

3c.

$m = \frac{y_1 - y_2}{x_1-x_2}\\$

$m = \frac{1 - (-3)}{-1-4}\\$

$m = \frac{4}{-5}\\$

$m = -\frac{4}{5}$

$m = \frac{y_1 - y_2}{x_1-x_2}\\$

So, I need to find the value of b but im very confused on how to! Can someone help me?

Angelina_Jolie [31]

b = 78°

The angles at a point sum to 360°

that is 45 + 237 + b = 360

282 + b = 360 ( subtract 282 from both sides )

b = 360 - 282 = 78°
