Answer 1

Answer:

15) Slope (m) = -7/5

16) Slope (m) = 0

17) Slope (m) = 1/0 (It's an undefined slope, in other words it's just a vertical line)

Step-by-step explanation:

Use this formula for each, to find slope⤵⤵⤵

$\frac{y {2} - y1}{x2 - x1}$

15) ⤵

$\frac{10 - 3}{ - 1 - 4} = \frac{7}{ - 5} = - \frac{7}{5}$

16) ⤵

$\frac{ - 5 - ( - 5)} {2 - 3} = \frac{0}{ - 1} = 0$

17) ⤵

$\frac{ 3 - 2}{ - 5 - ( - 5)} = \frac{1}{0}$

Hope this helps :)
