find the slope. *

1. (10, -16), (-7, -19)

a) \\(\frac{17}{3}\\) b) \\(-\frac{17}{3}\\)
c) \\(-\frac{3}{17}\\) d) \\(\frac{3}{17}\\)

Explanation:

Step1: Recall slope formula

The slope $m$ between two points $(x_1,y_1)$ and $(x_2,y_2)$ is $m=\frac{y_2-y_1}{x_2-x_1}$.

For problem 2:

Step2: Substitute points (14,-20), (-12,-20)

$m=\frac{-20-(-20)}{-12-14}$

Step3: Simplify numerator and denominator

$m=\frac{0}{-26}=0$

For problem 3:

Step2: Substitute points (10,-16), (-7,-19)

$m=\frac{-19-(-16)}{-7-10}$

Step3: Simplify numerator and denominator

$m=\frac{-3}{-17}=\frac{3}{17}$

Answer:

1. C) 0
2. D) $\frac{3}{17}$
