Answer:

1. \:  \:  \:  \:  \frac{1}{5}  \\ 2. \:  \:  \:  \:   - \frac{3}{2}  \\ 3. \:  \:  \:  \:  \frac{1}{2}

Step-by-step explanation:

1. In the first diagram we simply count the number of squares along the rise and the number of squares along the run as slope equals rise/run

2. we use the slope formula

\frac{y2 - y1}{x2 - x1}   = \frac{ - 2 - 1}{  1-  ( - 1)}  =  \frac{ - 3}{2}  =  -  \frac{3}{2}

3. pick any two points and apply the slope formula again

( - 1. \:  \: 1) \: and \: (3. \:  \: 3) \\  \frac{3 - 1}{3 - ( - 1)}  =  \frac{2}{4}  =  \frac{1}{2}

stepladder [879]

Answer:

39

Step-by-step explanation:

Angles are supplementary when they add up to 180.  So, we know the other angle that isn't 58 is 180-58=122.  Therefore, 122=3n+5\\3n=117\\n=39
